* refactor(skills): rebuild faceless-explainer + pr-to-video on the shot-sequence architecture Move both skills onto the current shot-sequence authoring architecture and the latest shared engine, then re-narrate to each domain. The engine fixes (pre-assembly frame guards + BGM loop-extend in assemble-index, dark-ground caption contrast, brand-accent selection + mono role in tokens, dark-mode polarity invert / weight-clamp / icon-font filter in build-frame) had only landed in one copy; both skills were a generation behind. - Authoring model: visual-design now writes a time-coded shot sequence (Scene windows paced to the voiceover) instead of the older effects-id phased note; motion-language carries the move vocabulary + the tightened motion doctrine (smooth over bouncy) + the seek-safe core (fromTo entrances, no CSS-transition motion); add cut-catalog (within-frame velocity-matched seams); frame-worker and SKILL Step 4/5 move to blueprint instantiation + shot-sequence fidelity. - faceless-explainer: fold the standalone composition.md into visual-design (inventing-the-visual / portrait / caption geometry); keep the explainer story doctrine; graft cue-segmented VO + candidate-blueprint-from-Step-3. - pr-to-video: keep the ingest pipeline (fetch-pr / ingest / fetch-people-avatars) and code-vocabulary; preserve the code-beat (code-* block as focal, Scenes choreograph the surround) and mechanism-beat treatments under the new model. - Drop stage-assets from both (no captured assets to stage); remove derivation references so each skill reads standalone. bun run scripts/lint-skills.ts passes; all scripts node --check clean. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * chore(skills): resync skills-manifest after format pass The pre-commit skills-manifest hook hashed the skills before the format hook reformatted cut-catalog.md, so the committed manifest lagged the on-disk content and CI's "Skills: manifest in sync" check failed.
