* 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).

# titlecard-reveal — Title-Card / Single-Card Reveal
|
||
|
||
**intent**: The calm breather/landing beat — one clean title or single brand/proof card revealed with exactly one restrained move (a slide-up crossfade, or a wipe-away-to-reveal), then a still hold. Low motion is the payload, not a deficiency.
|
||
|
||
**roles served**
|
||
|
||
- Benefits (from `benefits-titlecard-crossfade`, #34): a calm two-line value title card — headline value line, then one slide-up crossfade to a qualifier/elaboration line that holds center.
|
||
- Social_Proof (from `social-proof-reveal-card`, #35): wipe a busy app-collage open away with one diagonal pill-sweep to reveal a clean brand lockup (icon + wordmark) plus a centered "loved by [N]+ [audience] teams" social-proof line that spring-settles and holds.
|
||
|
||
**duration**: 3–5s (Benefits 3–4s; Social_Proof ~5s / observed 4.7s).
|
||
|
||
**shot structure**
|
||
|
||
```
|
||
Scene 1 (0.0–~0.4s): static camera on [neutral / dark background]. Establish the opening state.
|
||
Variant — Benefits: empty-to-text — [benefit line 1] is about to fade in centered (no busy open).
|
||
Variant — Social_Proof: a busy intro frame holds briefly — an [app-screenshot / use-case collage] of overlapping cards under a [setup line].
|
||
|
||
Scene 2 (~0.4–~1.5s): the ONE move executes — a single restrained reveal that brings the calm card to center.
|
||
Variant — Benefits: [benefit line 1] fades in centered while scaling slightly (~95%→100%, smooth ease-out) and holds.
|
||
Variant — Social_Proof: a large [accent-color] rounded pill sweeps diagonally bottom-left → top-right and exits the corner, clip-path wiping the collage away to reveal the [brand logo lockup] beneath as the [logo icon] strokes draw on.
|
||
|
||
Scene 3 (~1.5s–end): the revealed/settled card holds to the end (the allocated stillness). At most one subtle live element (a slow breathing pulse on the card, or a very slow camera drift). No second development phase.
|
||
Variant — Benefits: [benefit line 1] translates up and fades out as [benefit line 2 — qualifier / elaboration] translates up from below center and fades in to take center; holds. (This single slide-up crossfade IS the one move — Benefits front-loads no Scene-2 wipe.)
|
||
Variant — Social_Proof: the lockup — [logo icon] centered, [wordmark] below, centered [social-proof tagline] "Loved by [N]+ [audience] teams" (the [N]+ may count up) — spring-settles small, then holds.
|
||
```
|
||
|
||
**motion vocabulary**: single restrained reveal (gentle fade-in + subtle scale-up settle | diagonal clip-path pill-wipe), one slide-up crossfade between two centered lines (Benefits), icon stroke draw-on (Social_Proof), optional "[N]+ teams" count-up, logo+tagline spring-settle-and-hold, subtle breathing on the held card, hold-to-end. Calm register — no spring chains, no tumble, no per-beat flips, no second phase. Camera static (optional very slow drift only).
|
||
|
||
**rule mapping**
|
||
|
||
- gentle fade-in + subtle scale-up settle (Benefits Scene 2) → `rules/scale-swap-transition.md` (restrained in/settle; cross-reference the fade ease in `techniques.md`)
|
||
- single slide-up crossfade between two centered lines (Benefits Scene 3) → `rules/discrete-text-sequence.md` (one line hands off to the next; translate-up + crossfade)
|
||
- diagonal pill-wipe reveal (Social_Proof Scene 2) → `rules/techniques.md` (clip-path reveal masks — the wipe)
|
||
- icon stroke draw-on (Social_Proof Scene 2) → `rules/svg-path-draw.md`
|
||
- "[N]+ teams" count-up (Social_Proof Scene 3, optional) → `rules/counting-dynamic-scale.md`
|
||
- logo + tagline spring-settle-and-hold (Social_Proof Scene 3) → `rules/spring-pop-entrance.md` (single soft settle; intentionally one beat, not a chain)
|
||
- subtle breathing on the held card (the one live element during the hold) → `rules/sine-wave-loop.md`
|
||
|
||
**camera modifier**: optional — a single very slow drift/push under the hold only → `rules/multi-phase-camera.md`. Default is fully static; do not add unless the held beat would otherwise read as a freeze-frame.
|
||
|
||
**stillness note**: This is a legitimate allocated-stillness beat. The hold in Scene 3 is the deliverable, not an unanimated gap — do NOT manufacture a development phase, extra swaps, or force-animation. One restrained move + a subtle hold (optionally one breathing element or one slow drift) is the correct and complete shape.
