 - **Visible text is short motion-graphics copy** — headline / stat / one-word emphasis (`"$83K"`, `"INSTANT"`), never a sentence from the narration. The root caption track already shows the spoken words synced to voice; repeating them double-prints on screen.
 - **Build the whole shot — reveal across the full `duration`, never front-load.** Dumping the whole canvas in the first ~25% then holding it is exactly what reads as a PowerPoint slide. Instead reveal each piece — a line, a card, a stat, an icon — **as the `voiceover` reaches it**, sequencing reveals across the shot and especially the back ~50%, with the macro camera move running underneath. **Only EXITS are banned** — a non-final frame unmounts mid-frame, so an exit tween truncates and reads as a glitch (the root transition IS the exit); mid-shot reveals are free and seek-safe. The lone exception is a note marked as a deliberate hold / stillness frame: there, an entrance + a quiet settle is right (a held read beats bad motion).
 - **Implement the shot sequence faithfully — every Scene is a timeline phase.** The Scene lines ARE the build: map each Scene onto a phase of the one timeline, each piece revealing as the `voiceover` reaches it. For each **named motion** in a Scene, open its rule recipe under `RULES_DIR/<id>.md` and reproduce its mechanics — **never name-guess** (a guess loses the signature move). The **`blueprint:` template** (`../hyperframes-animation/blueprints/<id>.md`) gives the overall shape; read it and keep its **signature move** recognizable, then instantiate it with this frame's content / assets / timing. `compose` → no template; sequence the shot straight from the Scene lines. Whichever, never front-load the whole sequence at `t=0` — pace the reveals to the voiceover.
-- **Place each candidate by its `roles`** (the `focal` is the hero): a `cutout` is a foreground subject — respect the 83% keep-out, lay text around it, not over its face; a `background` is full-bleed and dimmed ~30–50% so foreground content stays legible. Frame files are sub-compositions. Audio remains orchestrator-owned: never author `<audio>` in a frame. An approved `[video]` candidate may be declared as a frame-local `<video data-frame-video="approved" data-start="..." data-duration="..." data-track-index="...">`; `assemble-index.mjs` hoists it to the host root and translates its timing. Do not use this declaration for audio, unapproved URLs, or videos without explicit timing. If no approved video is supplied, use an explicitly supplied static still/key art (`[video-still]` or another image candidate) as `<img>`; do not extract a frame, fabricate a URL, or silently embed an unapproved clip.

Give every approved video explicit host geometry with numeric `data-frame-video-x`, `data-frame-video-y`, `data-frame-video-width`, and `data-frame-video-height`; optionally set `data-frame-video-fit="cover|contain|fill|none|scale-down"` (default `cover`). The assembler converts only those values to host CSS: frame-local classes and inline styles do not cross the hoist boundary.
