 @* The single release-card grid for every browse surface (Sessions, Mixes, Cuts, Archive). Cards
    open a detail page; how a card computes its href is the only real divergence across surfaces, so

+     - DetailRoute (the simple default): every card links /{DetailRoute}/{entryKey} (Sessions, Mixes).
      - HrefResolver (per-card): each card links HrefResolver(release), so Archive routes each card by
        its own medium through the one ReleaseRoutes table, and Cuts routes to /cuts/{entryKey}.
    HrefResolver wins when both are supplied. The card subtitle defaults to the artist; SubtitleResolver
