+`parseError()` types `status` as a `number`, while Hono’s `c.json()` second argument expects `ContentfulStatusCode`. The cast matches what you already return at runtime and satisfies TypeScript.

 The error is captured and logged with both the custom context and structured error fields:

 Access the logger via `c.get('log')` in handlers. No `useLogger()` — use `c.get('log')` and pass it down explicitly, or use Express/Fastify/Elysia if you need `useLogger()` across async boundaries.
 
+Structured errors: throw `createError()`, then in `app.onError` use `parseError()` and pass `parsed.status as ContentfulStatusCode` to `c.json()` (Hono types the status argument as `ContentfulStatusCode`, not `number`).
