/* ═══════════════════════════════════════════════════════════════════════════
   reading-pm.css — rooms, trades, changes, the item drawer, the viewer hotspots and the
   block appended to a plan-reading question row (js/reading-pm.js).
   lane cc-impl-2 · 2026-10-10 · NEW FILE. css/styles.css is FROZEN, so this is a separate
   sheet and MUST load AFTER css/reading.css, whose .rdg- atoms it reuses. Every rule here
   is prefixed .rpm- and every colour is a design token (`:root` is the DARK palette,
   `:root.light` a CLASS on <html> overrides it). Nothing outside .rpm- is styled.
