/**
 * OpenAPI route table — populated incrementally.
 *
 * v1.4.23 baseline covers the routes the v1.5 iOS app touches end-to-end:
 *   - POST /api/auth/login
 *   - POST /api/auth/passkey/login-verify
 *   - POST /api/auth/refresh
 *   - GET  /api/measurements
 *   - POST /api/measurements
 *   - POST /api/measurements/batch    (W2 — Apple Health ingest)
 *   - POST /api/devices               (W3 — APNs registration)
 *   - GET  /api/insights/comprehensive
 *
 * Schemas come from `src/lib/validations/*` so the wire contract stays
 * single-source-of-truth. The `.meta()` annotations on each schema land
 * the title + description in `components.schemas.*` automatically.
 *
 * Routes are intentionally registered as inline operation objects
 * rather than via a wrapping helper — `zod-openapi`'s `createDocument`
 * type-checks the route table directly, which catches schema-shape
 * regressions at typecheck time.
