+# AI Agent Briefing
+
+## Mission & Scope
+- `@denkiyagi/fontkit` is our maintained fork of the upstream `fontkit`, powering typography in `yagisan-reports` (and downstream `@denkiyagi/pdf-lib`).
+- Versioning follows `2.0.4-mod.YYYY.N`. Every intentional divergence must land in `MODIFICATIONS.md` so downstream agents understand the API surface we guarantee.
+- Recent focus areas captured in `MODIFICATIONS.md`:
+    - Better Unicode variation selector (UVS) handling
+    - Richer shaping controls
+    - Vertical metrics accuracy
+    - Predictable type definitions for consumers
+
+## Repository Orientation
+- `src/` – Main implementation, mostly ESM `.js` files with `@ts-check`. Key areas: `glyph/`, `layout/`, `opentype/` (shapers, GSUB/GPOS logic), `tables/`, `subset/`, and entrypoints `index.ts` (browser) & `node.ts` (Node/fs helpers).
+- `types/` – Generated `.d.ts` output from `npm run build:types`. Never hand-edit.
+- `dist/` – Parcel bundles emitted by `npm run build:js` (CJS/ESM/browser targets). Never hand-edit.
+- `test/` – Mocha (ESM) regression suite plus `test/data/` font fixtures; keep fixtures stable and small.
+- `MODIFICATIONS.md` – Single source of truth for fork-specific behavior; update whenever behavior changes.
+
+## Toolchain & Commands
+- Use Node 20+ and npm (repo ships `package-lock.json`). Install with `npm install`.
+- Fast feedback loop:
+  - `npm run build:js` → Parcel build into `dist/`.
+  - `npm run build:types` → `tsc --project tsconfig-types.json` (follows `src/index.ts` & `src/node.ts`, pulls in JS via `allowJs`).
+  - `npm run mocha` → run tests without rebuilding.
+  - `npm test` → full build + mocha (what CI runs).
+  - `npm run coverage` → `c8 mocha`.
+- `npm run trie:*` → regenerate shaping tries (`src/opentype/shapers/*.trie` & companion `.json`) when Unicode data/scripts change; outputs are gitignored.
+- `npm run clean` removes build outputs—rerun builds before publishing or testing.
+
+## Coding Guidelines & Pitfalls
+- Preserve existing `// @ts-check` comments and JSDoc—they drive declaration output.
+- Prefer editing sources under `src/`. Touch `types/` or `dist/` only via build scripts.
+- When adding TS types or new exports, update `src/types.ts`, re-run `npm run build:types`, and ensure both `index.ts` and `node.ts` export the new surface.
+- Keep performance-sensitive code (e.g., cmap processing, shapers) allocation-free; mimic existing patterns (caching decorators, typed arrays).
+
+## Testing & Validation
+- Run `npm run mocha` only when `npm run build:*` has already refreshed `dist/` and `types/`; otherwise use `npm test` so the build step runs first (matches CI).
+- Use `npm run coverage` only when you need c8 instrumentation (slower but catches missed branches).
+
+## Data & Fixture Workflow
+- Unicode trie data (`src/opentype/shapers/*.trie` and `.json`) is generated; edit the source scripts (`generate-data.js`, `gen-use.js`, `gen-indic.js`) or `.machine` files, then re-run the matching `npm run trie:*` task locally (artifacts remain untracked per `.gitignore`).
+- The repository intentionally vendors select fonts under `test/data/`; do not rename paths without updating tests.
+- Avoid storing unrelated binaries in-tree—use temporary paths outside the repo for manual experiments.

+# Modifications
+
+## [Unreleased]
+
+- Remove WOFF format support
+    - Also removing the `tiny-inflate` dependency (the indirect dependency may remain)
+- Remove WOFF2 format support
+    - Also removing the `brotli` dependency
+- Remove DFont format support
+- Simplify the published TypeScript types by inlining the concrete format exports (`TTFFont`/`TrueTypeCollection`) in place of the old aliases (`Font`/`FontCollection`).
+- Remove the dependencies below by replacing them with new internal helpers (no API changes):
+    - `clone` (used by `TTFSubset`)
+    - `fast-deep-equal` (used by `CFFDict`)
+
+## [2.0.4-mod.2025.2]
+
+- Improve performance of `CmapProcessor#lookupNonDefaultUVS` by caching variation selector records from `cmap` format 14 subtable
+
+## [2.0.4-mod.2025.1]
+
+- Fix glyph mapping using the cmap format 14 subtable, improving support for UVS in methods like `TTFFont#glyphsForString`
+- Add `TTFFont#nonDefaultUVSSet`
+
+
+## [2.0.4-mod.2024.2]
+
+- Add properties to get the glyph's origin Y coordinate in the vertical writing mode:
+    - `TTFFont#defaultVertOriginY`
+    - `TTFFont#getVertOriginYMap`
+    - `Glyph#vertOriginY`
+- Fix data type of `version` property in `vhea` table
+- Fix properties `ascent`, `descent` and `lineGap` in `TTFFont` class so that they refer to `OS/2` table when `USE_TYPO_METRICS` flag is ON
+- Improve class `DefaultShaper` and its sub-classes
+    - Omit fractional features: frac, dnom, numr
+    - Move directional features to `ArabicShaper`: ltra, ltrm, rtla, rtlm
+    - Expose class `DefaultShaper` from `fontkit`
+- Improve `TTFFont#layout`
+    - Use named parameters
+    - Add parameter `shaper` to override shaping process
+    - Add parameter `skipPerGlyphPositioning` to skip calculating `GlyphRun#positions`
+- Fix fields `logErrors` and `defaultLanguage` in the top-level API
+    - Change to getter functions: `isLoggingErrors()`, `getDefaultLanguage()`
+- Expose type definitions
+
+
+## [2.0.4-mod.2024.1]
+
+- Removed

 # fontkit
 
 Fontkit is an advanced font engine for Node and the browser, used by [PDFKit](https://github.com/devongovett/pdfkit). It supports many font formats, advanced glyph substitution and layout features, glyph path extraction, color emoji glyphs, font subsetting, and more.
 
 ## Features
 
-* Supports TrueType (.ttf), OpenType (.otf), WOFF, WOFF2, TrueType Collection (.ttc), and Datafork TrueType (.dfont) font files
+* Supports TrueType (.ttf), OpenType (.otf), and TrueType Collection (.ttc) font files (WOFF/WOFF2/DFont inputs have been removed)
 * Supports mapping characters to glyphs, including support for ligatures and other advanced substitutions (see below)
 * Supports reading glyph metrics and laying out glyphs, including support for kerning and other advanced layout features (see below)
 * Advanced OpenType features including glyph substitution (GSUB) and positioning (GPOS)
