/* ══════════════════════════════════════════════════════════════════════
   Canvas Items + Watch Party Theater Mode

   Extraído de sidebar.css (Anti-Monolith Sección XIV) — el archivo
   principal había crecido a 1018 líneas mezclando estilos del sidebar
   verticales con la anatomía completa de stickies del canvas y el
   theater mode de Watch Party. Este archivo concentra:

     - Anatomía de canvas items (note, AI Q+A, action bars, stack picker)
     - Iterar + accordion de turnos (Sprint C v5.7.27.44)
     - Watch Party Theater Mode (rediseño Fase 7ac)

   sidebar.css queda con los estilos puros del nav vertical (grupos,
   labels, focus mine, espacios home, créditos pill).

/* [v5.7.27.124] Pill "Cargar mensajes anteriores" en flujo normal dentro
   del theater chat, no `position: absolute`. El comportamiento absolute
   es para el drawer principal (donde el pill flota sobre el scroll
   container), pero en el theater el chat es más compacto y el pill se
   superponía al header. Igual que el chat React del canvas, queremos el
   pill como elemento de bloque entre header y messages list.
