  "description": "When fixtures-feed.io responds with valid HTTP 200 but a malformed/unexpected JSON shape (e.g. an extra field, a missing 'fixtures' key, an empty array), the bracket page must NOT crash to a blank screen — show a recognisable degraded state with an explanation, NOT a React error overlay. Catches optimistic JSON parsers that assume the upstream is perfectly behaved.",
