   --------------------------------------------------------------------------
   Materials from a real construction office: drafting paper, blueprint, brushed
   steel, brass, engraved plates, backlit screens. Everything is drawn in CSS —
   no image files, no icon font, no external request.

   Light  = drafting paper on a desk, hardware in navy steel and brass.
   Dark   = graphite workshop, brushed metal, backlit displays.

   Brand tokens are the app's real ones:  --ink #0D0D63 · --accent #DE076E
   Every colour is a token with a dark value. No page may hard-code a hex.

   Class contract is UNCHANGED from the flat version — pages need no edits.
