   SADDLE — Landing v4
   "The page is one map."
   A single fixed WebGL survey renders the land, the route, the
   waypoints and the ink for the whole journey; the content beats
   are paper cards that travel over it. Material logic is the app's:
   parchment desk · warm-white paper · rose-gold leather · brass ink ·
   the app's own indigo route line.
   Light = "Saddle Soap" · Dark = "Greatcoat" (navy wool and brass).
