/**
 * Feature flags — per-project, optionally scoped to an environment.
 *
 *   GET    /flags?projectId=&environmentId=&limit=&offset=
 *   POST   /flags                      — create
 *   PATCH  /flags                      — update (body carries id)
 *   DELETE /flags                      — delete (body carries id)
 *
 * The API intentionally uses body-carried ids (instead of path params)
 * so callers can target a flag with a single round-trip regardless of
 * which environment it's bound to.
