/* ============================================================
   Design tokens
   Brand palette per the build brief. --sun (the prototype's
   bright yellow) is intentionally dropped: bold bands use the
   ink-blue --accent, and --accent-2 (earth orange) is used only
   sparingly for focus rings and small emphasis.
   Variable names mirror the prototype: --ground = page bg,
   --paper = raised surface.
