- MatchCard and IqdbCard are siblings in the library detail aside and
both used key={item.j_id}, so React warned about duplicate children
(J-81 twice). Their keys are now unique per card.
- The video pipeline no longer decides "this browser can't encode" from
a single getFirstEncodableVideoCodec probe with source dimensions.
It now probes Conversion.init with the real (even) output size across
codec candidates and hardware preferences, uses the first valid
configuration, and reports exactly what was tried when nothing works.
It also fails fast with a clear message if VideoEncoder is missing in
the worker.
