/* SCANCAT design tokens. World: a retail scanning hardware vendor's spec sheet.
   Palette is the art: pure black modules on pure white, one accent only, the red of a
   laser scan line. ink #000 / paper #FFF / ash #F1F1EF panel / dim #6E6E6E meta / beam #FF2E17.
   Type: JetBrains Mono 800 for every headline and label (scanner readout), JetBrains Mono 500
   for data and codes, IBM Plex Sans 400/600 for body prose (vendor brochure voice).
   Spacing scale: 8 / 16 / 24 / 40 / 72 / 112. Radius: 0 everywhere, this is equipment.
   Rules: 1px hairline, 3px for chassis. Motion: one 2.8s linear beam sweep, UI flips at 120ms. */
