/**
 * Motion sheet — the single style authority for a project's motion-graphics

 * per-clip style prose: the image carries what words describe badly (texture,
 * weight, spacing), the text carries what images cannot enforce (rules,
 * negatives, audio policy).
 *
 * This module is deterministic: validate/normalize/persist + the master-image
 * prompt composer. Creative authoring (the interview) lives in the mograph
 * skill; the artifact is the contract.
