/* ============================================================
   LITHOSPHERES.COM THEME v1
   Loads AFTER bingoboardtv's style.css and re-skins the site:
   new fonts, palette (deep space + violet/mint), depth & glow.
   All tool pages style via CSS vars, so overriding vars here
   re-themes every page at once.
