/* Prefixed (--ysd-*) for the same reason as games/lawn-man/styles.css:
   these can't collide with the main WordPress theme's own :root custom
   properties if this stylesheet is ever loaded alongside it. Values are
   pulled from the site's real Neon Frost V3 tokens (frost-cyan/script-red/
   star-gold) rather than an arbitrary one-off palette, since this game is
   thematically about ice/snow and the real tokens fit directly. The
   tropical-island *game* art (sky/sand/ocean themes, flavor colors) is
   drawn on canvas in src/render/ and is untouched by any of this — this
   file is chrome only: HUD, buttons, overlays, fonts. */
