* fix(lint): promote rules to errors with registry exemptions and false-positive fixes - Export isRegistrySourceFile/isRegistryInstalledFile from composition.ts - Add registry exemptions to google_fonts_import and font_family_without_font_face - Add registry exemption to requestanimationframe_in_composition - Fix timed_element_missing_clip_class: data-track-index alone no longer triggers - Fix caption_transcript_parse_error: balanced-bracket scanner replaces non-greedy regex - Fix missing_timeline_registry: skips sub-compositions and template-wrapped files - Fix scene_layer_missing_visibility_kill: strip JS comments before pattern matching - Fix gsap_css_transform_conflict: exempt from() alongside fromTo() - Fix gsap_from_opacity_noop: only fires when opacity value is actually 0 - Add regression test for data-track-index-only elements * test(lint): add regression tests for false-positive fixes Covers the 7 missing negative-case assertions flagged in PR review: - registry marker suppresses google_fonts_import + font_family_without_font_face - registry marker suppresses requestanimationframe_in_composition - isSubComposition suppresses missing_timeline_registry - scene_layer_missing_visibility_kill: fires, commented-kill fires, real kill suppresses - gsap_css_transform_conflict: from() exempt alongside fromTo() - gsap_from_opacity_noop: non-zero opacity (e.g. 0.5) is a valid reveal, not a noop Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(examples): fix warm-grain template to pass promoted lint rules - index.html: remove undeclared "Lexend" from font-family stack - intro.html: replace Google Fonts @import with bundled Inter font - captions.html: quote TRANSCRIPT keys for valid JSON + use Inter font Fixes CLI smoke CI failure after google_fonts_import, font_family_without_font_face, and caption_transcript_parse_error were promoted from warning to error. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(cli): resolve warm-grain from repo registry in dev mode + bundle at build getStaticTemplateDir now falls back to registry/examples/<id> in dev mode so CI smoke tests use the PR-branch copy instead of fetching from main. build-copy.mjs copies warm-grain to dist/templates/warm-grain at build time so packed CLIs can scaffold it offline. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * fix(examples): remove trailing comma from warm-grain TRANSCRIPT array JSON.parse rejects trailing commas (valid JS, invalid JSON). caption_transcript_parse_error was still firing because of the comma on the last entry after quoting all keys.
