   Left: normal CollectionView list (Tags column dropped, see
   collection-view.css). Right: one static synopsis card, no interaction.
   base.css isn't in scope for this session — .view.active is assumed to
   already establish a flex/height context (it did before this change,
   driving .collection-list's flex:1/min-height:0). .tbr-layout takes over
   that "fill remaining height" role since it's now the direct child. */
