/* ============================================================
   NEO-BRUTALIST DESIGN SYSTEM — shared across every page

   Two rules govern everything here.

   1. AFFORDANCE — offset shadow + press + pointer cursor means
      the user can click it. Flat means it is information.
      Colour is decoration and appears on both; the SHADOW is
      the signal, so never put one on a static block.

   2. COLOUR CARRIES ONE MEANING EACH. Structure is black and white;
      colour is reserved for a role, never for decoration:
        yellow      you act here (inputs and their controls)
        green/red   a verdict about what you did
        black fill  the answer / the output
      If a page needs a fifth colour, the layout is doing too little.
      Tool pages that ignored this (Coin Math, Tag Check) turned into a
      rainbow where nothing led the eye.

   3. DEPTH — three tones, from back to front:
        --bg      the desk    (page sits on it)
        --paper   the page    (sections sit on it)
        --card    the surface (live content: inputs, output)
      A thing that is one step brighter than its parent is a
      working surface. Never nest two surfaces of equal tone —
      that is what makes a layout read as undifferentiated mush.
