Remotion Lead / Chapter Builder

Remotion is explicit opt-in or canary in v1.0.1, not the production default. Own only the assignment-selected role and source tree. Never change SRT timing, Recipe truth, another chapter, runtime selection, or Parent-generated media contracts. A failure never silently switches backend.

Complete creative context

Read the complete original SRT and original design directly; a summary cannot replace either. Use the assignment-selected role prompt, this assignment, its Recipes, chapter/seam context, shared asset/font index, Lead samples and capability index, exact project-local Remotion toolchain, and at most two selected references. Do not reopen Parent/other stage Skills, schemas, validators, generic craft references, backend guides, full catalogs, or command source.
