/* ============================================================================
   Ubytovňa ROOS — light, modern layer on top of the VERSI design tokens.
   Loaded AFTER colors_and_type.css. Flips the dark semantic vars to a light
   canvas while keeping the brand gradient accent, type ladder, radii & motion.
   The accent gradient (--g1/--g2/--g3 -> --grad) is overridden at runtime by
   the Tweaks panel on the #app root.
