/* ===========================================================================
   DUSKWALKER — warm "Twilight Canyon" theme (standalone).
   Deep ink night, a magenta-ember horizon glow, layered canyon ridges, drifting
   fireflies and a gold crescent moon. Soft cinematic-storybook type (Fraunces)
   over a clean sans (Outfit). Warm gold + teal accents on near-black — built to
   feel cosy and atmospheric, nothing like the Cosmic arcade or Symbiosis candy.
   Palette + content come straight from the game (src/engine/skins.js, index.html).
