Adds decision guidance and conventions the 8-site regression test exposed as blind spots — agents had the capability but never reached for it. step-1-capture: - Clarify capture goes into <project-dir>/capture/ so capture artifacts stay isolated from later build files (SCRIPT/STORYBOARD/DESIGN/compositions/) - 7/8 regression tests already did this; codify as the convention step-4-storyboard: - Add "When to pick which" decision table for shader vs CSS vs hard cut transitions. Shader transitions were available but used in 0/8 tests — every test defaulted to CSS. The table frames shaders as "reveals, reaction shots, brand moments" vs CSS as "connective tissue" - Update technique count (10 → 11) step-6-build: - Mid-scene activity table gets a new row for audio-reactive logo/CTA animation (bass pulse, treble glow). Audio-reactive was used in 0/8 tests despite narration being present in all of them step-7-validate: - Snapshot section: explicit "use hyperframes snapshot, don't roll custom" with the default naming pattern spelled out. Stripe's run used custom ffmpeg naming (beat-6-cta-at-20.5s.png) instead of frame-XX-at-Ys.png - New render section: require --output renders/<project>.mp4 so final MP4s have predictable names. Without this, 7/8 tests produced wildly different filenames (preview.mp4, cal_2026-04-19_20-29-21.mp4, basecamp.mp4, etc.) techniques.md: - New technique #11: Audio-Reactive Animation. Covers the sampling pattern (per-frame tl.call, not single tween), when to use (music/dramatic VO videos), intensity ranges (3-5% for text/logos, 10-30% for backgrounds), and anti-patterns (equalizer bars, waveforms, strobing).
