// Daemon-side mirror of src/media/models.ts. The two files are kept in sync by hand — any model added to
// src/media/models.ts must be added here too. Drift is enforced by
// `node scripts/verify-media-models.mjs` (also exposed as
// `npm run verify:media-models`); CI should call it before publish so
// the moment one side adds a model and the other doesn't, the build
// fails with a precise diff.
