/* ── Anti-flash canvas (accessibility) ─────────────────────────────────────
   The dark look is painted by body::before (a fixed layer) and light-mode by a
   body class set by JS after load — so html/body themselves had NO solid colour.
   Chrome/Firefox honour color-scheme for the canvas, but SAFARI paints the canvas
   WHITE during navigation/iframe-load before body::before renders → a full-white
   flash on every dark-mode page switch. A white strobe is a photosensitive-seizure
   risk, so give html a solid dark base that paints on the FIRST frame (render-blocking
   CSS), before body::before or any JS. theme.js's pre-paint bootstrap adds .pref-light
   for light-mode users so they don't get the inverse (dark) flash. */
