/**
 * `static/openapi.json` is a JSON rendering of `static/openapi.yaml`, which is
 * itself generated from the protos (`pnpm --filter @openstatus/proto buf:openapi`).
 * Agents and OpenAPI tooling overwhelmingly expect `/openapi.json`; hand-editing
 * either file drifts them apart, which `openapi.test.ts` fails on.
 *
 * `openapi-yaml.ts` embeds the YAML as a module because tsdown flattens
 * `src/` into a single file: a path resolved from `import.meta.url` at runtime
 * would point at the bundle's directory, not the source module's.
 *
 * Run: `pnpm --filter @openstatus/server openapi:json`
