// Pattern-test for the CT-1768 fetch-mock `delayMs` (Robin/ubik2's suggestion):
// a mock can return after a fixed real-time delay, so a fetchJson isn't resolved
// instantly. The assertion's read is what starts the fetch, and the harness
// waits for the delayed response before it reads again, so the result is
// observed deterministically once it lands.
