Based on my search, here's what I found for LÖVE 2D rich text and text effects libraries:

## Rich Text Libraries for LÖVE 2D

### 1. **richtext** (gvx/richtext)
richtext is a text and image formatting library for the LÖVE framework. It uses a curly-brace tag syntax for inline formatting:

```lua
rt = rich:new{"Hello {green}world{red}, {smile} {big}Big text.", 200, ...}
```

### 2. **SYSL-Text**
SYSL-Text is a text animation and automatic wrapping library based on tags. This appears to be a library specifically designed for text effects and animation.

### 3. Forum Discussion on BBCode Syntax
The LÖVE community discussed using "BBCode-inspired tags, since [] do not require the shift key to type them." This was part of early discussions about rich text library design.

### Text Effects Approach
For text effects like flickering, fade-in/fade-out, and size changes, the tween.lua library can be used to gradually change the alpha value (it can be used to gradually move the text, and change its size, too).(no content)For changes in size, instead of creating lots of fonts with different sizes, create just one with max size, and change the zoom of the display with love.graphics.scale + love.graphics.push before drawing it.

### Resources
You can find more libraries in the awesome-love2d curated list, which includes FlexLöve, a fully featured GUI library, and other UI/text-related tools.

For the most up-to-date libraries, I'd recommend checking:

Here's what I found about HaxeFlixel text effects and FlxText rich text formatting:

## FlxText Overview

The most basic object to display text is a FlxText. You can easily set properties such as text, color, alignment and more. It is an extension of FlxSprite, which means you can do a lot of the same things with it.

## Rich Text Formatting with `applyMarkup()`

HaxeFlixel supports rich text formatting through the `applyMarkup()` method. This applies formats to text between marker characters, then removes those markers. NOTE: this will clear all FlxTextFormats and return to the default format.

Example usage from the API:
```haxe
text.applyMarkup(
    "show $green text$ between dollar-signs",
    [new FlxTextFormatMarkerPair(greenFormat, "$")]
);
```

You can use multiple format markers like: `text.applyMarkup("Hey @Buddy@, what <g>is<g> going @on<g>?<g>@", [yellow, green]);`

## FlxTextFormat

FlxTextFormat supports font color in 0xRRGGBB format. It can also set whether the text should be bold (must be supported by the font), which is false by default.

Here are the search results for Phaser 3 text effects, bitmap text, rich text, and BBCode:

## BBCode Text Plugin (Rex Rainbow)

The rexBBCodeText plugin allows drawing text with BBCode protocol.(no content)You can use it like: `scene.add.rexBBCodeText(x, y, '[b]h[/b]ello')` with style options for font family, size, and color.

Key features:

- Tags between `[esc]...[/esc]` or `[raw]...[/raw]` will be treated as content (escape feature).
- You can set the delimiter `[]` to another custom value in the style of constructor.
- Supports word or character wrapping with modes: `'none'`, `'word'`, `'char'`/`'character'`, or `'mix'`.

## Bitmap Text (Built-in Phaser)

There are two classes: BitmapText and DynamicBitmapText. They are both "dynamic" in the sense that you can change the text contents at any time. The difference is that DynamicBitmapText has callbacks for per-character rendering effects and scrolling.(no content)Under WebGL, Bitmap Texts are extremely fast to render and you don't incur any speed penalty when updating their content because the underlying texture doesn't change. You can also create visually impressive fonts by preparing them in an image editor, applying fills and any other effect required.(no content)Because they are drawn from a texture, you are more limited in what you can do with them. For example, you cannot do things like apply a stroke or fill pattern to a Bitmap Text.

## Dynamic Bitmap Text Effects

Dynamic Bitmap Text objects invoke a callback for each letter being rendered during the render pass. This callback allows you to manipulate the properties of each letter being rendered, such as its position, scale or tint, allowing you to create interesting effects like jiggling text, which can't be done with Static text.

## Character Tinting

Character tinting is a WebGL only feature and only works with Static Bitmap Text, not Dynamic. The tint works by taking the pixel color values from the Bitmap Text texture, and then multiplying it by the color value of the tint. You can provide either one color value for the whole character, or individual corner colors.

## Typewriter Effect

The core concept behind a typewriter effect is to add 1 character from a string to a Text object at a consistent interval until all the characters are added.(no content)The same core concepts for creating a typewriter effect work for Text, BitmapText, and DynamicBitmapText!

Here are the search results for Defold text effects, rich text, GUI label markup:

## Defold-RichText Library

Defold-RichText is a system to create styled text based on an HTML inspired markup language.(no content)It creates rich text GUI nodes from text containing markup.

### Key Features
The RichText library will create GUI text nodes representing the markup in the text passed to the library. It will search for tags and split the entire text into words, where each word contains additional meta-data that is used to create and configure text nodes. This means that the library will create as many text nodes as there are words in the text.

### Settings Options

- The settings table can contain values like width (maximum width of a line of text - omit to present entire text on a single line), position (the position that the text aligns to), which defaults to 0,0 if not specified.
- Vertical alignment options include richtext.VALIGN_TOP, richtext.VALIGN_MIDDLE and richtext.VALIGN_BOTTOM, defaulting to VALIGN_TOP. This defines how the words of a line of text are positioned vertically.
- The combine_words setting can be set to true to combine words with the same style on a line into a single node, useful for very long texts where the maximum number of nodes would exceed the GUI limit.

### Markup Example
The library supports tags like `<size>`, `<color>`, `<font>`, `<outline>`, `<shadow>`, `<b>`, `<i>`, `<img>`, and `<p>` for paragraph spacing.

## Native Defold GUI Text Nodes

Defold supports a specific type of GUI node that allows text to be rendered in a GUI scene. Any font resource added to a project can be used for text node rendering. The fonts that you wish to use in GUI text nodes must be added to the GUI component.(no content)To change the font of a text node, use the gui.set_font() function. To change the line break behavior, use gui.set_line_break(). To change the content, use gui.set_text().

## Label Components

Defold's GUI supports text but it can be tricky to place GUI elements in the game world. Labels make this easier. To create a Label component, right click the game object and select Add Component ▸ Label.(no content)You can set the text of a label at runtime using `label.set_text("#my_label", "New text")`.

Here's what I found about Ren'Py text effects, rich text tags, and text styling:

## Official Ren'Py Text Tags

Ren'Py contains several ways of displaying text. The say and menu statements are primarily concerned with the display of text to the user. The user interface often contains text, displayed using the text, textbutton, and label screen language statements.

### Basic Text Tags
You can use text that is {b}bold{/b}, {i}italic{/i}, {s}struckthrough{/s}, or {u}underlined{/u}.

### Additional Built-in Tags

- The `{a}` text tag can link to a website or jump to a label.
- The `{cps}` text tag makes text type itself out slowly, even if slow text is off.
- The `{font}` tag changes the font.
- The `{k}` tag changes kerning. It can space the letters of a word closer together or farther apart.
- The `{size}` tag changes the size of text. It can make text bigger or smaller, or set it to a fixed size.
- The `{space}` tag adds horizontal space in text. The `{vspace}` tag adds vertical space between lines.

### Style Text Tags
Ren'Py supports text tags that access styles. These are text tags where the tag name is empty. In this case, the argument is taken to be the name of a style. For example, the {=mystyle} tag will access the mystyle style.(no content)You can use text tags to make a particular string use a style: "{=date_s}8/17{/=date_s}" Though it is important to note that style text tags don't support Outlines.

## Custom Text Tags

Ren'Py has support for defining your own text tags. These text tags can manipulate the text and text tags defined within, including adding and removing text and other text tags. Custom text tags are created by assigning a text tag function to an entry in one of the following dictionaries.(no content)A text tag function takes three arguments: The tag itself, the argument for the tag, and a list of content tuples.

Based on my searches, I found general information about Cute Framework's text rendering capabilities, but the specific API documentation for `cf_draw_text` markup effects like shake and wave was not directly returned in the search results. Here's what I found:

## Cute Framework Text Rendering Information

Cute Framework focuses on "applying custom markup effects on text (like shaking, or dynamically glowing)" as part of its text rendering capabilities.(no content)CF provides APIs for all of these in its draw API.

Links: [{"title":"A Tour of CF Renderer - Cute Framework","url":"https://randygaul.github.io/cute_framework/topics/renderer/"},{"title":"Cute Framework","url":"https://randygaul.github.io/cute_framework/"},{"title":"Virtual File System - Cute Framework","url":"https://randygaul.github.io/cute_framework/topics/virtual_file_system/"}]

Based on the search results, here's what I found about Cute Framework's text markup code effects:

The framework focuses on things like "word-wrapping, vertical vs horizontal layout, measuring the width/height of a text blurb, applying custom markup effects on text (like shaking, or dynamically glowing)."(no content)If you want to draw sprites, lines/shapes, or text, the documentation points to `cute_draw.h`.(no content)The CF renderer design offers a very high-performance batching solution, unifying rendering sprites, shapes, and text all together. It also offers shader customization that can be applied to renderable items (as well as canvases).(no content)Cute Framework is described as "the cutest framework available for making 2D games in C/C++."

The search results give an overview of the text markup capabilities (custom effects like shaking and glowing text), but for more detailed code examples and documentation on implementing specific text effects, you may want to visit the full documentation at randygaul.github.io/cute_framework/ or check the `cute_draw.h` header file directly.

     4→
     5→### C Side — Font Infrastructure & Glyph Drawing
     6→
     7→The C side provides the **basic font loading and glyph rendering primitives**. It doesn't know about effects, tags, or rich text — it just draws glyphs efficiently.
     8→
     9→**1. Font Loading**
    10→```c
    11→// Load TTF via stb_truetype, bake glyphs to texture atlas
    12→font_load(name, path, size)
    13→
    14→// Optionally: bitmap font support (spritesheet + metrics JSON)
    15→font_load_bitmap(name, image_path, metrics_path)
    16→```
    17→- Bake glyphs to texture atlas on load
    18→- Store per-glyph metrics: advance width, bearing, UV coords in atlas, size
    19→- Font registry by name (like layers)
    20→- Default font loaded at startup (for error screen)
    21→
    22→**2. Glyph Metrics Queries**
    23→```c
    24→font_get_text_width(font_name, text)    // Width in pixels
    25→font_get_height(font_name)              // Line height
    26→font_get_glyph_metrics(font_name, char) // {width, height, advance, bearing_x, bearing_y}
    27→```
    28→- Used by YueScript for layout calculations
    29→- These are called during text formatting, not per-frame

   161→```
   162→
   163→This clean separation means:
   164→- C handles the **GPU-facing work** (atlas management, batched rendering)
   165→- YueScript handles the **game-facing work** (parsing, layout, effects)
   166→- Effects are infinitely flexible — they're just YueScript functions modifying character properties before the C draw call

Based on the search results, here's what I found about using multiple BBCode effects on the same text in Godot's RichTextLabel:

## Built-in Animated Effects

Godot's RichTextLabel supports built-in BBCode animated effects like `[tornado radius=5 freq=2]Tornado Effect[/tornado]` and `[shake rate=5 level=10]Shake Effect[/shake]`.

## Nesting Multiple Effects

The effects can be used like any other BBCode, and nesting is possible. For example: `[sparkle c1=red c2=yellow c3=black][cuss]Hecking[/cuss] Cool Sword[/sparkle]` - this demonstrates combining multiple effects on the same text by nesting the tags.

## Custom BBCode Effects

You can extend the RichTextEffect resource type to create your own custom BBCodes. You begin by extending the RichTextEffect resource type, and add the tool prefix to your GDScript file if you wish to have these custom effects run within the editor itself.(no content)The currently installed custom effects are stored as an array of RichTextEffects. To add a custom effect, it's more convenient to use `install_effect`.

## Third-Party Solutions

There's a community addon called `teeb.text_effects` that provides simple BBCode elements to use in RichTextLabels, along with `teeb.text_transitions` for text animations.(no content)A better version for Godot 4+ is also available.

## Creating Custom Shake Effects

Users have created custom shake effects by extending RichTextEffect, using code like:
```gdscript
tool extends RichTextEffect
var bbcode = "myshake"
```
with parameters accessible via `char_fx.env.get()`.

   926→1. **Simple effects should be simple** — a one-liner wave effect shouldn't require boilerplate

   928→3. **Word-level and character-level** — effects can target words or characters
   929→4. **Regions for interactivity** — hover/click detection on text spans
   930→5. **Tree integration** — characters are objects, can use timers/springs/etc.

  1043→### Effect API
  1044→
  1045→Effects can be **functions** (simple, stateless) or **setup functions** (stateful, using `^` and `/`).
  1046→
  1047→#### Simple Function Effect
  1048→
  1049→Called every frame. No state, just modifies character properties.
  1050→
  1051→```yuescript
  1052→-- Signature: (c, args, ctx) ->
  1053→-- c: character object (or word if scope=word)
  1054→-- args: parsed arguments {[1], [2], ..., key=val}

  1057→effects.wave = (c, args, ctx) ->

  1060→  c.oy += sin(ctx.time * freq + c.local_i * 0.5) * amp

  1062→
  1063→#### Stateful Effect (using ^ and /)
  1064→
  1065→For effects that need state, use `^` to initialize and `/` to add an action. Called once per character when text is created.

     8→
     9→| Area | Decision | Rationale |
    10→|------|----------|-----------|
    11→| Renderer | OpenGL | Smooth rotation, additive blending, performance headroom, console-portable |
    12→| Audio | miniaudio + stb_vorbis | Single-header, pitch shifting, OGG support |
    13→| Physics | Box2D 3.1 | Already used, true ball-to-ball collisions needed |
    14→| Scripting | Lua 5.4 + YueScript | Build-time compilation with `-r` flag for line numbers |
    15→| Timestep | Fixed 120Hz physics, 60Hz render | Decoupled for pixel-perfect visuals with responsive input |
    16→| Resolution | Per-game configurable | 480×270, 640×360, or custom; aspect-ratio scaling with letterboxing |
    17→| C Structure | Single anchor.c | Monolithic file, easier navigation |
    18→| Resources | Live forever | Games are small enough; no unloading needed |
    19→| Linking | Static | No DLLs; SDL2, Lua, audio all compiled in |
    20→| Distribution | Single executable | Zip-append for game content, extractable by modders |
    21→

  1593→### 9.1 Font Loading (C Side)
  1594→- [ ] Support both bitmap fonts (pixel-perfect) and TTF (scalable)
  1595→- [ ] TTF: Load via stb_truetype, bake glyphs to texture atlas
  1596→- [ ] Bitmap: Load from spritesheet with metrics file
  1597→- [ ] Support multiple sizes per font (separate atlases)
  1598→- [ ] Store glyph metrics (advance, bearing, size)
  1599→- [ ] Error screen shows full stack trace (file:line for each call)
  1600→
  1601→### 9.2 Glyph Rendering (C Side)
  1602→- [ ] Draw single glyph at position with transform and color
  1603→- [ ] Return glyph metrics to Lua for layout

  1591→**Goal:** Font loading, metrics, and glyph rendering in C. Per-character effects handled later in YueScript.
  1592→
  1593→### 9.1 Font Management
  1594→- [ ] `font_load(name, path, size)` — Load TTF via stb_truetype, bake glyphs to texture atlas
  1595→- [ ] `font_unload(name)` — Free font resources
  1596→- [ ] Font registry by name (like layers)
  1597→- [ ] On-demand glyph baking to atlas
  1598→
  1599→### 9.2 Font Metrics
  1600→- [ ] `font_get_height(font_name)` — Returns font line height
  1601→- [ ] `font_get_text_width(font_name, text)` — Returns pixel width of UTF-8 string
  1602→- [ ] `font_get_char_width(font_name, codepoint)` — Returns advance width for single codepoint
  1603→- [ ] `font_get_glyph_metrics(font_name, codepoint)` — Returns full metrics (width, height, advance, bearingX, bearingY)
  1604→
  1605→### 9.3 Drawing
  1606→- [ ] `layer_draw_text(layer, text, font_name, x, y, color)` — Draw UTF-8 string (simple case)
  1607→- [ ] `layer_draw_glyph(layer, codepoint, font_name, x, y, r, sx, sy, color, alpha)` — Draw single glyph with transform (for per-character effects)
  1608→
  1609→### 9.4 Implementation Details
  1610→- [ ] Use stb_truetype for TTF loading and glyph rasterization
  1611→- [ ] Glyphs baked to texture atlas on-demand
  1612→- [ ] Glyphs batch with existing sprite system (same atlas approach)
  1613→- [ ] UTF-8 decoding for text width measurement and iteration

Here are the search results for FreeType Windows x64 MSVC static library prebuilt downloads:

## Key Options Found:

### 1. **ShiftMediaProject/freetype2 (GitHub)** - Best for MSVC Static Libraries
These libraries are available for each supported Visual Studio version with a different download for each version. Each download contains both static and dynamic libraries to choose from in both 32bit and 64bit versions.

- **URL:** https://github.com/ShiftMediaProject/freetype2

### 2. **ubawurinna/freetype-windows-binaries (GitHub)** - Official Reference
Windows binaries of FreeType. The freetype libraries use the Universal CRT and therefore requires Visual C++ 2015-2022 Redistributable to be present on system.

- **URL:** https://github.com/ubawurinna/freetype-windows-binaries

### 3. **Official FreeType Source**
The FreeType source code bundle contains project files for various versions of Microsoft Visual C++ and Visual Studio for x64, Windows 32, and Windows CE. However, these files have been contributed and might be out of date, thus use them with care.

- **URL:** https://freetype.org/download.html

### 4. **Build via vcpkg** (Alternative Approach)
This page details the steps involved in building/installing static freetype while the rest of the dependencies of forge are dynamic libraries. You can customize vcpkg triplets to build a static FreeType library:
This command will build and install a static version of freetype unlike earlier.

- **URL:** https://github.com/arrayfire/forge/wiki/Static-freetype-library-in-x64-windows-triplet-of-vcpkg

### 5. **GnuWin32** (Older Versions)
Windows binaries of FreeType can also be downloaded directly from this download page (version 2.3.5) of the GnuWin32 project, or from GTK's download page (version 2.4.2).

- Note: These are older versions and may not meet your needs.

**Recommendation:** The **ShiftMediaProject** repository is likely your best option for prebuilt static libraries specifically compiled with MSVC for Windows x64.

I cannot provide the exact download URL for the release asset based on the content provided. While the page shows "FreeType 2.14.1" release information with hash values for DLL files, the actual asset download links are not visible in the text content shared. The page indicates "Assets 2" are available, but states "There was an error while loading. Please reload this page," preventing access to the downloadable files.

To obtain the download URL, you would need to visit the GitHub release page directly at: `github.com/ubawurinna/freetype-windows-binaries/releases/tag/v2.14.1`

Based on the JSON content provided, **there are no download URLs available** for this release.

The `assets` field in the response is an empty array: `"assets":[]`

While the release page references specific files (freetype.dll and freetype.lib for both win32 and win64 configurations, plus static library variants), the actual `browser_download_url` fields are not present in this API response. To access the downloadable binaries, you would need to visit the GitHub release page directly at: https://github.com/ubawurinna/freetype-windows-binaries/releases/tag/v2.14.1

     8→
     9→| Area | Decision | Rationale |
    10→|------|----------|-----------|
    11→| Renderer | OpenGL | Smooth rotation, additive blending, performance headroom, console-portable |
    12→| Audio | miniaudio + stb_vorbis | Single-header, pitch shifting, OGG support |
    13→| Physics | Box2D 3.1 | Already used, true ball-to-ball collisions needed |
    14→| Scripting | Lua 5.4 + YueScript | Build-time compilation with `-r` flag for line numbers |
    15→| Timestep | Fixed 120Hz physics, 60Hz render | Decoupled for pixel-perfect visuals with responsive input |
    16→| Resolution | Per-game configurable | 480×270, 640×360, or custom; aspect-ratio scaling with letterboxing |
    17→| C Structure | Single anchor.c | Monolithic file, easier navigation |
    18→| Resources | Live forever | Games are small enough; no unloading needed |
    19→| Linking | Static | No DLLs; SDL2, Lua, audio all compiled in |
    20→| Distribution | Single executable | Zip-append for game content, extractable by modders |

    11→1. **Locate the session transcript** — find the most recent JSONL file
    12→2. **Convert to Markdown** — use a lowercase, hyphenated title slug (e.g., `engine-phase-1.md`). Date-based filenames don't work with Blot.
    13→3. **Read the converted log** to review the full session, especially if compacted. Summary must cover everything.
    14→4. **Write a detailed summary:**
    15→   - Chronological order (matching conversation flow)
    16→   - Weight to one-off fixes, attempts, problems solved
    17→   - Specific details: error messages, what was tried, what worked
    18→5. **Create a short title** (max 30 characters)
    19→6. **Show title + summary to user** — wait for approval before proceeding
    20→7. **Prepend title + summary** to the log file (replace default header)
    21→8. **Sync context files**
    22→9. **Commit** with title as subject, full summary as body:
    23→
    24→   **CRITICAL:** Copy summary text directly from the log file. Do not retype. The commit body must be character-for-character identical to the log file.

     5→> Hi, Claude. Let's get started on phase 9. The text module for Anchor has two parts to it: the C side and the YueScript side. The C side should be responsible for the basics of drawing text. While the YueScript side is responsible for complex features that allow the application of arbitrary effects to text. These are done by drawing the text character by character, each character being a full Anchor object (in the tree), and then applying functions to each character based on the effect desired via the use of a tagging system. You can see the implementation for this in the text.lua file in either of the Anchor projects in the reference/ folder.
     6→> 
     7→> What I'd like you to do is read the implementation plan, read the files in the Anchor projects, read ANCHOR.md, and then separate what needs to be the C side and the YueScript side. Then show this idea to me. After that, I'll have you research how other engines implement their rich text systems so you can integrate your findings into our plan.
     8→
     9→I'll read the implementation plan, ANCHOR.md, and the text.lua files from the reference projects to understand what needs to be separated between C and YueScript.

   511→**Structural &amp; Linking:**
   512→- `{a}` - Creates hyperlinks to URLs, labels, or screens
   513→- `{image}` - Inserts images inline with text
   514→- `{space}` and `{vspace}` - Add horizontal/vertical spacing
   515→
   516→**Text Formatting:**
   517→- `{b}` - Bold text
   518→- `{i}` - Italic text
   519→- `{u}` - Underline text
   520→- `{s}` - Strikethrough
   521→- `{plain}` - Removes bold, italics, underline, strikethrough
   522→
   523→**Visual Effects:**
   524→- `{color=#rrggbb}` - "Renders text in specified color"
   525→- `{alpha=value}` - Controls opacity (0.0-1.0)
   526→- `{size=value}` - Adjusts text size absolutely or relatively
   527→- `{outlinecolor}` - Changes outline/shadow colors
   528→- `{font=filename}` - Applies specific font
   529→- `{k=value}` - Adjusts character kerning

  4003→
  4004→**Options:**

  4006→1. **Use FreeType** - The proper solution. Larger dependency but correct. It can load embedded bitmaps directly from TTF files.
  4007→
  4008→2. **Use a bitmap font format** - BMFont, etc. Pre-rendered sprite sheet + metadata. Sidesteps TTF entirely.
  4009→
  4010→3. **Check if stb has something** - There's `stb_truetype` but no embedded bitmap support. No other stb font library handles this.
  4011→
  4012→My recommendation: **Add FreeType**. It's what LÖVE uses, it's battle-tested, and it handles pixel fonts correctly. The embedded bitmap support means pixel fonts "just work" at their native sizes.
  4013→
  4014→Want me to replace stb_truetype with FreeType? It'll require:
  4015→- Adding FreeType as a dependency
  4016→- Rewriting font_load to use FT_Load_Char with FT_LOAD_TARGET_MONO for pixel-perfect rendering
  4017→- Or using FT_LOAD_RENDER with embedded bitmap detection

     3→## Summary
     4→
     5→Implemented Phase 8 (Random) of the Anchor engine — a complete seedable PRNG system for deterministic gameplay and replay support, plus Perlin noise.
     6→
     7→**API Research:**
     8→- Researched random/RNG APIs across 17 game engines: LÖVE, Unity, Godot, Construct 3, HaxeFlixel, Heaps, Ceramic, Cute Framework, Phaser, p5play, PixiJS, Defold, FNA, KaboomJS, GameMaker, MonoGame, LÖVR
     9→- Created comprehensive research document at `reference/phase-8-random-research.md`
    10→- Identified common patterns: core generation, seed/state management, convenience functions, weighted selection, noise
    11→
    12→**Design Decisions:**
    13→- Algorithm: PCG32 (fast, excellent quality, 64-bit state for easy replay save/restore)
    14→- API style: Flat global functions (not `an:method()` style)
    15→- Ranges: All inclusive [0, 1], [min, max], [0, 2π]
    16→- Multiple instances: All functions accept optional RNG argument, defaulting to global
    17→- Noise: Perlin via stb_perlin.h
    18→
    19→**Implementation (7 steps):**
    20→- Step 1: PCG32 core — state struct, seed function, next function, global instance
    21→- Step 2: Basic generation — `random_float_01`, `random_float`, `random_int`
    22→- Step 3: Seeding/state — `random_seed`, `random_get_seed`, `random_create` (userdata with metatable)
    23→- Step 4: Convenience — `random_angle`, `random_sign(chance?)`, `random_bool(chance?)`
    24→- Step 5: Distribution — `random_normal(mean?, stddev?)` via Box-Muller transform
    25→- Step 6: Array functions — `random_choice`, `random_choices` (unique picks), `random_weighted`
    26→- Step 7: Perlin noise — integrated stb_perlin.h, `noise(x, y?, z?)` returning [-1, 1]
    27→
    28→**Testing:**
    29→- Added comprehensive tests to main.lua alongside existing physics simulation
    30→- Verified determinism (same seed = same sequence)

    27→2. `stbtt_PackSetOversampling(1, 1)` — Still smooth because stb_truetype always rasterizes vector outlines
    28→3. Thresholding > 127 — "still looks off"
    29→4. Thresholding > 0 — "bolded, extra pixels where they shouldn't be"

While the YueScript side is responsible for complex features that allow the application of arbitrary effects to text. These are done by drawing the text character by character, each character being a full Anchor object (in the tree), and then applying functions to each character based on the effect desired via the use of a tagging system.

   301→That's a few hundred C calls for a long text block, but only at creation time.
   302→
   303→**So the clean separation is:**
   304→- **C**: Font loading, glyph metrics, drawing
   305→- **YueScript**: Parsing + layout + effects (they're all part of "text intelligence")
   306→
   307→The alternative would be C exposing a monolithic `font_format_text(text, width, align)` that also strips tags, but then you'd have two implementations of the tag syntax — one in C for layout, one in YueScript for effects. That's worse.
   308→
   309→Does that reasoning make sense, or do you see a cleaner way to split it?
   310→
   311→> Yes. Now, please, research the following engines for how they handle their rich text systems. If you see any engine that has differences in how they handle their equivalent of the C side system, also surface it. But I'm primarily looking for API designs for the rich text system. The setup I have going on with these per-character effects is powerful, but it has a few drawbacks. For instance, doing effects on entire words feels counterintuive, like an underline effect whenever the mouse hovers over a word. There are lots of issues like that, so I'm looking for better APIs across that board that handle as many problems related to effects with text properly. Research across these engines: LÖVE, Unity, Godot, Construct 3, HaxeFlixel, Heaps, Ceramic, Cute Framework, Phaser, p5play, PixiJS, Defold, KaboomJS, GameMaker, MonoGame, LÖVR, Ren'Py, RPG Maker, GDevelop. Be thorough, take as much time as you need.
   312→
   313→I'll research rich text systems across all these engines. This will take several searches to be thorough.

     5→> Hi, Claude. Let's get started on phase 9. The text module for Anchor has two parts to it: the C side and the YueScript side. The C side should be responsible for the basics of drawing text. While the YueScript side is responsible for complex features that allow the application of arbitrary effects to text. These are done by drawing the text character by character, each character being a full Anchor object (in the tree), and then applying functions to each character based on the effect desired via the use of a tagging system. You can see the implementation for this in the text.lua file in either of the Anchor projects in the reference/ folder.
     6→> 
     7→> What I'd like you to do is read the implementation plan, read the files in the Anchor projects, read ANCHOR.md, and then separate what needs to be the C side and the YueScript side. Then show this idea to me. After that, I'll have you research how other engines implement their rich text systems so you can integrate your findings into our plan.
     8→
     9→I'll read the implementation plan, ANCHOR.md, and the text.lua files from the reference projects to understand what needs to be separated between C and YueScript.

   508→
   509→## General Text Tags
   510→
   511→**Structural &amp; Linking:**
   512→- `{a}` - Creates hyperlinks to URLs, labels, or screens
   513→- `{image}` - Inserts images inline with text
   514→- `{space}` and `{vspace}` - Add horizontal/vertical spacing
   515→
   516→**Text Formatting:**
   517→- `{b}` - Bold text
   518→- `{i}` - Italic text
   519→- `{u}` - Underline text
   520→- `{s}` - Strikethrough
   521→- `{plain}` - Removes bold, italics, underline, strikethrough
   522→
   523→**Visual Effects:**
   524→- `{color=#rrggbb}` - "Renders text in specified color"
   525→- `{alpha=value}` - Controls opacity (0.0-1.0)
   526→- `{size=value}` - Adjusts text size absolutely or relatively
   527→- `{outlinecolor}` - Changes outline/shadow colors
   528→- `{font=filename}` - Applies specific font
   529→- `{k=value}` - Adjusts character kerning

5500→No, the current implementation does **not** support Unicode beyond ASCII. Here's why:
  5501→
  5502→**Current limitations:**
  5503→
  5504→1. **Atlas only contains ASCII 32-127** (96 characters):
  5505→   ```c
  5506→   #define FONT_FIRST_CHAR 32
  5507→   #define FONT_NUM_CHARS 96
  5508→   ```
  5509→
  5510→2. **Text rendering skips non-ASCII**: When `layer_draw_text` encounters a codepoint outside 32-127, it simply skips it:
  5511→   ```c
  5512→   if (codepoint >= FONT_FIRST_CHAR && codepoint < FONT_FIRST_CHAR + FONT_NUM_CHARS) {
  5513→       // draw glyph
  5514→   }
  5515→   // else: silently ignored
  5516→   ```
  5517→
  5518→3. **UTF-8 decoding works**, but the decoded codepoints have nowhere to go since Japanese characters (Hiragana U+3040+, Katakana U+30A0+, Kanji U+4E00+) aren't in the atlas.
  5519→
  5520→**What would be needed for Japanese:**
  5521→
  5522→- **Option A**: Pre-bake a huge atlas with all needed Unicode ranges (impractical for CJK - thousands of characters)
  5523→- **Option B**: Dynamic glyph caching - load glyphs on-demand as they're encountered, evicting old ones when the atlas fills up. This is how most engines handle CJK text.
  5524→
  5525→Option B is the standard approach. It would require restructuring the font system to use a glyph cache with a hash map from codepoint → glyph info, and rendering glyphs to the atlas lazily.
  5526→
  5527→> Let's do option B in another session, then. Please build the web version so I can test it.

     3→## Summary
     4→
     5→Implemented Phase 9 (Text Rendering) of the Anchor engine — font loading, metrics, and glyph rendering on the C side, with FreeType for proper pixel font support.
     6→
     7→**API Design Work:**
     8→
     9→The session began with extensive API design before implementation:
    10→- Analyzed C vs YueScript separation — C handles font loading, metrics, and glyph drawing; YueScript handles tag parsing, layout, and per-character effects
    11→- Layout stays in YueScript because it's intertwined with tag parsing (the `|` character triggers line breaks, spaces inside tagged regions have different wrapping rules, tag delimiters get stripped)
    12→- Researched rich text systems across 19 game engines: LÖVE, Unity, Godot, Construct 3, HaxeFlixel, Heaps, Ceramic, Cute Framework, Phaser, p5play, PixiJS, Defold, KaboomJS, GameMaker, MonoGame, LÖVR, Ren'Py, RPG Maker, GDevelop
    13→- Key findings: tag syntax varies widely (HTML-style, BBCode, curly braces, markdown-style, escape codes), effect application models differ (per-char callback vs per-char objects vs custom effect classes), word-level grouping and named regions are useful patterns
    14→- Created `reference/phase-9-text-analysis.md` with full research and recommendations
    15→- Designed imaginary API with 10 built-in effects (wave, shake, rainbow, typewriter, fade, pulse, jitter, swing, scramble, bounce) — this exercise helped define what C needs to expose
    16→- Rewrote API in YueScript following Anchor conventions: `^` for properties, `>>` and `<<` for tree flow, multiple `()` parentheses for multiple effects on same text span
    17→
    18→**What Was Built:**
    19→- `font_load(name, path, size)` — Load TTF via FreeType, bake 512×512 RGBA glyph atlas
    20→- `font_unload(name)` — Free font resources
    21→- Font registry by name (like layers), max 16 fonts
    22→- `font_get_height(font_name)` — Returns line height
    23→- `font_get_text_width(font_name, text)` — Returns pixel width of UTF-8 string

    25→- `font_get_glyph_metrics(font_name, codepoint)` — Returns x0, y0, x1, y1, advance
    26→- `layer_draw_text(layer, text, font_name, x, y, color)` — Draw UTF-8 string
    27→- `layer_draw_glyph(layer, codepoint, font_name, x, y, r, sx, sy, color)` — Draw single glyph with transform

# Anchor Phase 9

## Summary

Implemented Phase 9 (Text Rendering) of the Anchor engine — font loading, metrics, and glyph rendering on the C side, with FreeType for proper pixel font support.

**What Was Built:**

- `font_load(name, path, size)` — Load TTF via FreeType, bake 512×512 RGBA glyph atlas
- `font_unload(name)` — Free font resources
- Font registry by name (like layers), max 16 fonts
- `font_get_height(font_name)` — Returns line height
- `font_get_text_width(font_name, text)` — Returns pixel width of UTF-8 string
- `font_get_char_width(font_name, codepoint)` — Returns advance width for single codepoint
- `font_get_glyph_metrics(font_name, codepoint)` — Returns x0, y0, x1, y1, advance
- `layer_draw_text(layer, text, font_name, x, y, color)` — Draw UTF-8 string
- `layer_draw_glyph(layer, codepoint, font_name, x, y, r, sx, sy, color)` — Draw single glyph with transform

**Filter Mode Changes:**

- Renamed `set_shape_filter` → `set_filter_mode` (global setting for shapes and fonts)
- Added `get_filter_mode()` to query current mode
- Default changed to "rough" for pixel-perfect rendering
- Fonts respect filter mode at load time (rough = 1-bit mono, smooth = 8-bit grayscale)

**Wrong Avenues (stb_truetype):**
The initial implementation used stb_truetype, which led to failed attempts at pixel-perfect rendering:

1. Basic `stbtt_BakeFontBitmap` — Produced anti-aliased glyphs ("looks very smooth")
2. `stbtt_PackSetOversampling(1, 1)` — Still smooth because stb_truetype always rasterizes vector outlines
3. Thresholding > 127 — "still looks off"
4. Thresholding > 0 — "bolded, extra pixels where they shouldn't be"
