   HERO.CSS — Sprint 1 (Refined)
   Creative direction for the Hero only: "Neo Futuristic Premium Digital
   Portfolio" — Apple / Vercel / Linear / Framer / Stripe reference class.
   Sophisticated gradients, soft ambient light, glassmorphism, floating
   depth. No neon, no cyberpunk, no heavy dark UI. This does not change
   the sitewide token set in style.css — every new color/material below
   is scoped to `.hero` via local custom properties, so Nav / About /
   Craft / Work / Education / Contact are unaffected until their sprint.

   ATMOSPHERE
   Three soft, blurred gradient blobs (aurora) drifting slowly behind a
   faint dot-grid — this is what replaces "heavy dark UI" with ambient,
   modern light. Nothing here is decorative filler: the aurora is the
   Hero's primary lighting source and the grid signals "engineered,"
   both load-bearing for the Neo-Futuristic read.

   A floating glassmorphic "product card" replaces the flat monogram
   frame: real stack (C++ / OpenGL / Web pulled straight from the site's
   own meta description), a live status row, and a small trend line —
   it reads as evidence of shipped work, not decoration. A soft aurora
   orb sits behind it for depth; three tag chips float at staggered
   heights/phases around it for layered depth and gentle premium motion.
