   THEME: Ma — negative space as the material
   ══════════════════════════════════════════════════════

   Washi-grey paper (light) or sumi (dark), one vermilion seal. Space does
   the work: two columns, 64px between photos, an asymmetric offset, slow
   fades and no hover transforms. The only Japanese device is tategaki —
   the hero subtitle set vertically on desktop. */
