/*
  Open Dungeon Master site. The palette, type and surface treatments are the
  app's arcane-night theme (src/app/globals.css in the server repo): deep
  indigo neutrals, aged gold accents, ember for heat. The ambient layers
  (topographic contours, dust motes, starfield) are the app's furniture too.
  Nothing here recreates the app UI; it dresses a marketing site in the same
  brand.
