/**
 * Request-body validation for the watcher routes.
 *
 * Each handler validates with `parseBody`, so a malformed body is rejected
 * with a `BadRequestError` (→ 400) instead of the raw `ZodError` a bare
 * `.parse()` surfaces — which neither adapter maps, so it becomes a 500.
 * Validation runs before the watcher store is touched.
 *
 * These handlers are synchronous, so `parseBody` throws during the call —
 * hence `expect(() => …).toThrow` rather than the `.rejects` form.
