// Plugin HTTP route adapter for serving approved custom-widget assets.

// Registered with `auth:"plugin"` because sandboxed iframes carry no device
// token. The authenticated gateway mints a scoped asset capability first; the
// route validates it on every request. This adapter only translates the request;
// all capability, jail, approval, and header logic lives in `serve.ts`.
