@* Release Archive: one card per ReleaseMedium, driven off Enum.GetValues + a display-metadata table.
   No hardcoded three-arm switch in markup — adding a medium surfaces a new card automatically and only
   needs one new entry in MediumCards below. Card idiom mirrors CmsGenreBrowser (MudCard + swatch). *@
