/* Ironstack review studio - dark BIM-exhibit chrome (reference: root room-3d.html).
   Token-driven: consumes the custom properties each viewer page defines on :root
   (--bg/--panel/--ink/--mut/--cyan/--line/--lblbg/--panelbg/--chipbg/--mono, plus
   floor3d's --scal/--scalbd/--issred/--flagink; var() fallbacks carry pages that do
   not define those). Dark is the default; body.light mirrors the reference light set.
   Where a page styles the same selector inline, this sheet either leaves the
   selector to the page entirely (see the per-section notes), restates the
   page's own values, or aligns the selector to the reference exhibit
   (root room-3d.html) - never a third design - and adds only what the page
   does not declare (injected UI, hover states, touch guards, light mirrors);
   the page's higher-specificity body.light mirrors keep winning. */
