* feat(skills): product-launch-video + consolidate motion knowledge into hyperframes-animation
- Add the product-launch-video skill: shot-sequence architecture where each
visual frame is a time-coded shot sequence picked from a blueprint menu and
paced to the voiceover (anti-PowerPoint). Includes the frame-worker sub-agent,
story/visual/motion-design references, and audio/captions/transitions/
stage-assets/assemble-index scripts.
- Consolidate motion knowledge in hyperframes-animation as the single source of
truth: promote the updated atomic rules (31 -> 36) and rename product-launch-
video's archetypes into hyperframes-animation blueprints (13 -> 15, replacing
the old set). product-launch-video, faceless-explainer, and pr-to-video now
reference them via ../hyperframes-animation/{rules-index,blueprints-index}.md
and the rules/blueprints dirs. Fixes the discrete-text-sequence broken links;
blueprints no longer ship per-id runnable examples, so example references in
the consumers were dropped.
- Default HeyGen TTS voice to Marcia (deterministic; was the API's first English
voice, which drifts on catalog re-sort). Override with --voice.
- assemble-index pre-assembly frame guards: auto-repair a sub-comp root missing
canvas dims; hard-fail on <video>/<audio> inside a sub-comp; hard-fail on a
timed non-root element missing class="clip" or overlapping same-track clips.
- Lint/CLI: lint media inside sub-compositions as an error; stop false-positive
caption layout/lint findings; contrast/layout-audit skip elements hidden by an
invisible ancestor.

* fix(skills): clear CodeQL alerts in assemble-index.mjs
- script/style blanking regex now matches closing tags with trailing
whitespace (</script >, </style >) — js/bad-tag-filter (high).
- drop the existsSync precheck before reading/repairing a frame file; read
directly and handle ENOENT, removing the check->write TOCTOU window —
js/file-system-race (high).

# comparison-split — Comparison Split-Cards
|
||
|
||
**intent**: Two paired items of equal weight shown side-by-side with mirrored 3D "book-open" tilts — the eye reads them as a balanced comparison, then a pill badge lands at each card's inner edge to punctuate. The motion IS the symmetry: two cards arriving from opposite wings into a held spread.
|
||
|
||
**roles served**
|
||
|
||
- Key_Feature (from `comparison-split-cards`): when two complementary features / capabilities of equal weight should be presented **simultaneously, not sequentially** — an A/B, a "X + Y together," paired concepts the viewer must weigh side-by-side. Not for >2 items (use `grid-card-assemble`) or sequential steps.
|
||
|
||
**duration**: 4–6s
|
||
|
||
**shot structure** (a `[bg]` canvas carrying two faint ambient glow blooms — `[accent A]` near 30%, `[accent B]` near 70% — so each side owns a color identity across a 50% symmetry axis; equal-width cards under one shared perspective parent)
|
||
|
||
- **Scene 1 (0.0–~0.8s) — title sets the concept.** A centered `[title line]` with an `[accent keyword]` slides DOWN into place from just above (a short smooth settle). The downward arrival is deliberate: it forms a non-conflicting T-shape against the cards, which arrive from the sides next.
|
||
- **Scene 2 (~0.4–1.9s) — the split-tilt entry (signature move).** Two equal-width feature cards arrive from opposite wings — `[left card]` from the left, `[right card]` from the right ~0.2s behind — each carrying a **mirrored 3D `rotateY` tilt** (left faces right, right faces left, opening like a book) and scaling ~0.85→1 as it lands. The entry overlaps the title's tail so the whole thing reads as ONE arrival, not two beats. Each card holds `[image / label / subtitle]`; box-shadows fall **outward** from the tilt (left shadow right, right shadow left).
|
||
- **Scene 3 (~1.9–end) — badges punctuate, then hold.** A pill `[badge]` lands at each card's **inner edge** (left then right, ~0.3s apart), overlapping its card ~15% so it reads as attached, not orbiting. This is the lone overshoot in the shot — it earns the punctuation. Settles and holds.
|
||
|
||
**motion vocabulary**: title slide-down from above; mirrored opposite-wing card entry; static book-open `rotateY` tilt (`+tilt` left, `−tilt` right); tilt-matched outward box-shadow; inner-edge badge spring-pop; gentle phase-opposed idle float (left vs right, never synchronized) registered as subtle jitter; dual side-glow ambient.
|
||
|
||
**rule mapping**
|
||
|
||
- two cards entering from opposite wings with mirrored `rotateY` tilts + tilt-matched shadow → `split-tilt-cards` (the signature; keep the two-layer split so the entry `x`/`scale` and the idle never collide on one alias)
|
||
- title slide-down settle → `gsap-effects` (translate + opacity on a long-tail `power3`)
|
||
- inner-edge pill badge pop (the one overshoot) → `spring-pop-entrance` (overshoot register — earns the punctuation)
|
||
- phase-opposed idle float on the pair → `sine-wave-loop` (low-amplitude register — subtle jitter, NOT lazy breathing; left `sin(t)`, right `sin(t+π)` so they never conveyor-belt)
|
||
- the two faint side glows behind the cards → `ambient-glow-bloom` (un-triggered soft bloom, one per accent)
|
||
|
||
**camera modifier**: camera-static by default — the symmetry is the subject and a move would break the balance.
