/* ═══════════════════════════════════════════════════════════════════════════
   道をつくる · journey-composer-desktop.css — the EDIT BENCH (重ね, the lens
   sheaf). Pixel-faithful port of design-mockups/desktop-home-genkan/
   composer-final.html onto a production overlay room.

   Level model: #journeyBenchRoot is a fixed overlay one step above the shelf
   room (z 9580 over 9550, under the hall toast's 9600), gated by
   body.bench-room. Beam chrome (.genkan-beam,
   .gb-*) comes from home-hall.css; this file adds only the room-label + way-
   back pieces the hall's bare beam doesn't carry. Everything else is scoped
   under .bench-room-root so nothing leaks into the rooms beneath.

   Tokens only; gold appears ONCE (the seal's hang ring). Small informational
   text uses --color-faint-warm (AA at these sizes — the PR-3 fleet's rule).
