/* ══════════════════════════════════════════════════════════════
   Room slider — turns a room built from vw/vh-positioned elements
   into a fixed-size "stage" that pans horizontally on portrait /
   vertical viewports, instead of squeezing everything into a
   narrow stacked layout. The nav bar stays outside this wrapper
   so it never moves.

   Usage in a room page:
     1. Include this file + room-slider.js.
     2. Wrap every room element (everything except .room-nav and
        any modal/popup overlays) like so:
          <div class="room-scroll"><div class="room-stage">
            ...room-lines, back-wall, wall art, characters...
          </div></div>
     3. In that room's own <style>, change any vw -> cqw and
        vh/dvh -> cqh used to POSITION those elements (rules that
        already use % or custom properties for --bw-* need no
        change — percentages resolve against the stage automatically).
     4. Optionally set --room-stage-width on :root to tune how wide
        the virtual room is when panned (default 1300px).
