/* ───────── SUMI · ink on washi (loaded last, wins over every older look) ─────────
   Warm washi paper with fibres, sumi ink for text and lines, one vermilion seal colour for what
   matters. Headlines in a brush-cut Mincho, body in a calm Gothic. The navigation is a hanging
   scroll on the right: one kanji seal per tool. Panels are sheets of paper with a brushed top edge;
   hovering one presses a small red seal into its corner. */
