/* Octanks: bright paper, like the tanks' own art. Cream page, white cards, ink type, with amber and
   magma as the fuel. Amber is a fill colour here, never text: on paper it is too light to read, so
   links and small accents use --accent, a burnt orange. Motion is decorative and switches off with
   prefers-reduced-motion; nothing on the page depends on it. */
