Official UEFA Champions League metadata
- Replaces the shipped Champions League dependency on API-Football with UEFA's official public fixture feed.
- Requires no UEFA account, subscription, or API key.
- Adds Official UEFA as a reusable Metadata provider with previews and production refreshes.
- Preserves full club identities, stable match/team IDs, kickoff times, rounds, venues, crests, and stadium artwork.
- Prioritizes release-friendly canonical club aliases while retaining formal UEFA names.
- Keeps API-Football available as an optional provider for plans with current-season access.
Verified with 142 passing tests and a live 2026/27 UEFA fixture-feed smoke test.
