Motion Doctrine (Gateway)
Read this before composing any animation. It decides WHAT happens at every seam and how every scene performs; the technique skills implement it. These rules supersede generic / upstream motion guidance. The failure this prevents: scenes authored in isolation — the eye's momentum dies at every cut, and scenes wobble in place between entry and exit.
Route map
| Decision (this skill) | Implementation skill |
|---|---|
| Seam transition choice + parameters + code | cut-the-curve §1–5 (the catalog) |
| Text / element entry cascades | cut-the-curve §6 (waterfall entry) |
| In-scene group repositioning (no cut) | cut-the-curve §7 (nudge curve) |
| Cursor-led action / scene kickoff / morph ignition | oversized-cursor |
| Seam render mechanics / white-flash guard | seam-craft |
| Product-launch / explainer / caption work | overlays text-beat-economics, brand-faithful, captions-overlay on top of the upstream skill |
Authoring order: vector ledger (ledger.json) → STAMP the master seams from it
(scripts/seam-stamp.mjs --ledger ledger.json --write index.html) → sustained-motion
route per phase → carriers and causes → build comps → VERIFY (scripts/seam-gate.mjs).
Hand-author only Tier-A morphs/match-cuts; stamped seams pass the gate by construction.
