   canvas: 320-430px mobile first; wide screens keep the centered phone
           frame, so the fixed header and bottom bar never leave it
   palette: #9400D3 violet | #F8F8FF ghost | #6A5ACD slate |
            #ECF0F1 mist | #0E1621 ink
   voice:   monospace accents over a regular reading font, lightly
            rounded cards, compact buttons, pure-image game tiles with
            a short name underneath, conclusion-first reading rhythm,
            full-width main CTA, color-only state changes
