Repo cleanup: fix .gitignore, process 11 new fonts from To Sort, remove duplicates

- Fix .gitignore: use correct .DS_Store pattern, add __pycache__/, *.pyc, .pytest_cache/, Icon?
- Remove tracked Icon file from git
- Add 11 new fonts: copixel, depixel, fresh-christmas, introvert, lazare-grotesk, neopixel, pixel-crash, pixel-gamer, pixel-grid, qraydom, space-rabbit
- Remove duplicate pixelon from To Sort
- Clean up empty Webfonts directory in depixel
- Clear processed fonts from To Sort
- Add CLAUDE.md for Claude Code guidance
- All 934 tests passing

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## What This Is
+
+A Homebrew tap for custom fonts. Users `brew tap` and then `brew install font-<name>`. The repo contains font assets in `font_files/` and generated Ruby formulae in `Formula/`.
+
+## Commands
+
+```bash
+# Add or update a font (cleanup + formula generation + tests + brew audit)
+uv run add-font <path_or_name>
+uv run add-font <path_or_name> --no-test --no-audit
+
+# Run tests
+uv run pytest tests/ -v --tb=short
+
+# Run a single test file
+uv run pytest tests/test_font_structure.py -v
+
+# Run tests for a specific font
+uv run pytest tests/ -v -k "font-acrylic-hand"
+
+# Regenerate all formulae (without the full add-font flow)
+python3 .fontfoldercleanup/create_homebrew_formula.py
+
+# Reorganize font folders only
+python3 .fontfoldercleanup/cleanup_font_folders.py --path font_files
+```
+
+## Architecture
+
+- **`font_files/font-<name>/`** — Each font has exactly 4 subdirs: `ttf/`, `otf/`, `web/`, `other_files/`. No other top-level files allowed.
+- **`Formula/font-<name>.rb`** — Generated Ruby formulae. **Never edit by hand.** Edits go in `.fontfoldercleanup/create_homebrew_formula.py`.
+- **`tap_cli/main.py`** — The `add-font` CLI entry point. Copies font to `font_files/`, runs cleanup script, runs formula generator, then runs tests and `brew audit`.
+- **`.fontfoldercleanup/cleanup_font_folders.py`** — Sorts loose font files into `ttf/`, `otf/`, `web/`, `other_files/` subdirs.
+- **`.fontfoldercleanup/create_homebrew_formula.py`** — Scans `font_files/font-*` and writes one `.rb` per font. Contains `HomebrewFormulaGenerator` class and `formula_name_to_class()` for Ruby PascalCase conversion.
+- **`tests/`** — Parametrized pytest suite. Tests validate: folder structure, formula existence, formula content (paths, class name), no orphan formulae, no duplicates.
+- **`To Sort/`** — Staging area for new downloads not yet processed.
+
+## Formula Naming Convention
+
+`font-<name>` → Ruby class `Font<PascalCase>`. Split on hyphens/underscores, capitalize each part:
+- `font-acrylic-hand` → `FontAcrylicHand`
+- `font-graham_hand` → `FontGrahamHand`
+
+## Key Constraints
+
+- Python 3, standard library only (pathlib, shutil, argparse, re). pytest is the sole dependency.
+- Formulae download from `http://clancy.genet-godzilla.ts.net:3002/Fonts/homebrew-fonts/archive/main.tar.gz` and expect the archive to unpack as `homebrew-fonts-main/`.
+- CI runs `uv run pytest` on push/PR to main, plus `brew audit` on macOS (non-blocking).
+- `PROJECT.md` is the canonical project description. When updating project rules, update `PROJECT.md` first, then sync `.cursorrules`, `.github/copilot-instructions.md`, and `.claude/skills/project-context/SKILL.md`.
