   404HZ app — one product, one colourway: GRAY.
   field #bdbdc3 + ink #2921cc (v33). the ramp is
           ink-alpha — white alphas fail AA on the gray field,
           measured: i2 .92 = 4.68:1, i3 .90 = 4.56:1 (v33:42–43).
   Shared tokens + Origin @font-face live in
           ../design-system/tokens.css (imported first, below).
   type  : Origin Display 900 wordmark · Origin Text for panels,
           rows, labels and controls.
   layout: landing = one giant mark + scan rail. tool = search
           bar across the top, section nav on the left,
           one panel per screen. a fixed
           player band runs the bottom of every screen.
   texture: the square lattice canvas behind the landing hero.
           Tool panel grounds are
           PLATES: one rect per region, cut from the lattice by
           a 1px hairline edge — the lattice never ends ragged.
   motion : landing logo hover-rotate / 500ms / settle ease,
           dead under reduced motion. scan rail width ease.
           nothing loops.
   forbid : gradients · glow/blur/shadow · cards/pills · extra
            hues · solid CTA · admin tables · marketing grid.
