/* ── Room page — small screens ──
   The sidebar (six sections deep — Primary actions, View, Inspection
   Mode, Secondary actions, Legend & Stats, Inspector) switches from a
   docked side panel to a bottom sheet, same content, just re-anchored to
   the bottom of the viewport. Unlike the old single-purpose inspector,
   this sheet now holds every control the room page has, so it defaults
   COLLAPSED to a small handle (see .sheet-handle / setSheetOpen() in
   room.js) rather than staying permanently open — the floor plan stays
   the dominant thing on screen until the checker actually pulls the
   sheet up, and selecting a device or arming Inspection Mode opens it
   automatically so nothing relocated here becomes harder to reach. */

/* ── Editor page — small screens ──
   The editor now shares room.html's own .workstation/.floor-pane/
   .inspector-panel classes (see editor.html/editor.css), so the 700px
   block above already stacks it the same way: canvas first, full-width
   sidebar below. The one thing that needs overriding here is
   .inspector-panel's collapsed-bottom-sheet treatment — that assumes a
   .sheet-handle toggle button the editor doesn't have, so its whole Room/
   Tools/Properties/View/Legend/Help sidebar would otherwise shrink to an
   unreachable 72px sliver with no way to reopen it. Reverted back to plain
   static in-flow content instead: the sidebar just stacks below the canvas
   at full width and scrolls with the page. */
