/* Item reader (item #3465). The drawer behavior stays shared with the portal,
   while this sheet owns My Maestro's presentation boundary. The navigation
   snapshot below intentionally mirrors the portal reader as of the tabbed,
   single-canvas redesign; keeping it here lets My Maestro retain (and evolve)
   its own header treatment without silently drifting when portal CSS changes.
   Loaded after chat.css/mission.css so these rules use My Maestro's palette.
   The reader's actions ("Open in portal", "Pop out") ride the drawer's own
   ⋯ menu, so there is no host bar to style. */
