   GAMIFY · REDESIGN (2026-10-10) — the Home redesign canvas, built into the shell.
   Source: design/home-redesign (Main, Library, Profile boards, app.css).
   Loaded after skin.css, shell.css and desktop.css, so it wins on the shell only.
   Games keep their own skins: these variables live on body.shell, not :root.
   Backgrounds: body.shell[data-bg] = sky | sunset | meadow | lavender | night.
