/* HUA HUA, the house. Layout only: every colour, face and corner is a token of Kaleidoscope's huahua lens
   (kit/lens-huahua.css). The home is one Garamond on warm paper, after the style LNK pointed at on 2026-11-05: a giant
   word that comes into focus letter by letter and runs off both edges, a cover rising through it, six paths as covers,
   one night band, and a letter. The covers and cards are pictures, so they wear .day and stay paper in any light; their
   words are the lens's words on ink. The night band wears .ink. The page around them follows the light. */
