"""Curated extractor — known-good 24/7 F1 channels via direct embed URLs.

Returns a small, hand-picked list of embed URLs that are reliable enough to
be served as fallback "always-on" streams when the dynamic extractors find
nothing (e.g. between race weekends, when API providers are down).

These are direct embed URLs. The frontend routes them through /embed so the
iframe-stripping proxy bypasses any frame-buster JS in the upstream player.
