   Gienie — landing site styles
   Light identity: white surfaces, forest-green typography, the
   brand greens kept as accents and purple as sparkle accents.
   The hero carries a graph-paper grid that fades at the edges;
   the browser mockup intentionally keeps the original dark
   canvas palette so it pops as the focal object.
   Pure CSS, system font stack, no external resources.
