1. Catalog failure safety: warn when catalog is empty or throws, so capture doesn't silently produce zero images 2. Dead path: extract-audio-data.py → skills/gsap/scripts/ (was skills/hyperframes/scripts/) 3. --json fonts compat: emit both `fonts` (string[]) and `fontsDetailed` (FontToken[]) to avoid breaking external consumers 4. Restore .cursorrules writing alongside AGENTS.md + CLAUDE.md 5. .gitignore: remove over-broad `projects/` and `videos/` entries, keep scoped `cursor-tests/` and `launch-video*/` 6. agentPromptGenerator: mark unused params as reserved with comments, remove _animations from buildPrompt 7. Cookie filter: threshold 20 → 8 chars to preserve footer copy like "© 2026 Stripe" (16 chars) and "Privacy & Terms" (15 chars) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
