/* Toon Tone sale page.
   Standalone stylesheet: the page shares the game's tokens (paper, ink,
   Outfit) but none of its chrome or advertising surfaces.
   Colour is the subject, so the eight ring colours from the logo do the
   structural work (one per section) and the only elevated surface is the
   hero demo. Lists and rules instead of cards. */
