// AZ-460 — e2e companion for the annotation save URL + payload contract.
//
// AC-1 (FT-P-07): the doubly-prefixed canary URL on the real `annotations/`
//                 service. The fast-profile fixture asserts the URL via MSW;
//                 here we observe the real network request to confirm the
//                 service does not silently strip the `/annotations` prefix.
// AC-2 (FT-P-08): captured POST body contains all required fields. Today this
//                 is `test.fail()` (drift documented in fast tests).
//
// This e2e requires the suite docker-compose stack
// (`docker compose -f e2e/docker-compose.suite-e2e.yml up -d`) plus parent-suite
// `:test` images. It will run on the suite-e2e CI lane once those images are
// available; on a developer host without the stack the test skips with the
// standard message.
