/* Nexus Video Engine: the shared full-page layout for video tools (9 Oct 2026, timeline redesigned the same day).
   Same family as the Media Engine (Image Studio) and reuses its shared buttons, loader, toast and "ready" card
   from media-engine/engine.css. Layout:
     top bar · left rail (library) · library drawer · preview · inspector drawer
     full-width timeline: one bar (edit tools · play controls · zoom), track names on the left, time 0 at the left,
     only the playhead moves while playing.
   Phones: preview, the same timeline with icon-only track names, a big-button dock, drawers as bottom sheets. */
