Miguel ÁngelandClaude Opus 4.6 ef64063947 feat(skills): add hyperframes-fonts skill for font management
Adds a comprehensive font skill covering:
- How the deterministic font compiler works (embedded database + aliases)
- Full embedded font database reference table (11 families + aliases)
- Step-by-step guide to download and add custom fonts via @font-face
- Why Google Fonts @import fails in Docker and how to fix it
- Safe default font recommendations by use case
- CJK font handling (download woff2, single weight to manage size)
- Emoji platform differences (macOS vs Docker/Linux)
- Troubleshooting: unresolved fonts, tofu boxes, first-frame fallback
- Sub-composition font loading (per-file @font-face, ../ paths)

This teaches agents to always download fonts locally rather than relying
on Google Fonts CDN, preventing the most common render failure in
Docker/offline environments.
