/* Sandfold site. Tokens from projects/sandfold/DESIGN.md ("Courtyard at Dusk"), as built in
   app/src/main/java/org/sonicon/sandfold/ui/theme/Color.kt: Material roles light ("Lime-wash")
   and dark ("Dusk"): background, onBackground, onBackgroundMuted, surfaceContainer(+High),
   primary/onPrimary, tertiary, outline. The field tokens are fixed in both themes, as in the app:
   thresholdStone/edge for the stone bands, chalk for text on stone, diyaFlame for accents on
   stone, swept earth and marigold for the decorative bunting. Baloo 2 (display, variable wght
   400-800) over Mukta (body 400/600). Powder colours are never used for text on the light ground;
   spills and muddied shapes never use the error role (DESIGN.md). */
