+ * rationale as the auth/accounts/econ/match/playersettings workers: a reverse-engineered
+ * protocol, lenient handlers, no runtime validation.
+ *
+ * Do NOT add `.meta({ id })` to these schemas — with this hono-openapi + zod v4 setup a
+ * meta'd schema used in a response emits a `$ref` the framework doesn't always hoist
+ * into `components.schemas`, leaving a dangling reference. Leaving meta off makes every
+ * schema inline, which renders correctly in any tool.
