/**
 * Mirror JSON Schemas from `packages/core/schemas/` into `docs/schema/` so
 * Mintlify serves them at `https://hyperframes.heygen.com/schema/*`. The core
 * copies stay authoritative — they're exported from `@hyperframes/core` for
 * npm consumers — and this script is the single contract that prevents the
 * docs mirror from drifting.
 *
 * Usage:
 *   bun run sync-schemas         # copy core → docs
 *   bun run sync-schemas --check # exit non-zero if copies are stale (CI)
 *
 * `docs/schema/hyperframes.json` is authored directly in docs (no source in
 * core) so it's skipped by this script.
