/* KinDojo public site, redesign 2026-10-20.
   Light only, on purpose: the app is dark because it is a game at night on a phone; the site is paper.
   Tokens: washi paper from the Dojo's shoji screens, charcoal ink, one dojo-red accent, slate for links,
   and the app's own belt ladder as the single lively element (thin bands, never backgrounds). */
