 *
 *  Rationale by method:
 *    - GET/DELETE: parameters + 2xx response — the request itself has
 *      no body, so that's what the reader needs to see first.
 *    - POST/PUT/PATCH: request body + 2xx response — the shape to send
 *      is the main question; parameters and code samples are
 *      secondary, available one click away.
 *    - Other (HEAD/OPTIONS/…): be conservative, open nothing extra
 *      beyond responses. */
