   ToolVerse AI — Main Stylesheet
   Premium DARK SaaS visual system (2026) — glassmorphism, glow, motion.
   Inspired by Vercel / Linear / Stripe / Framer / Notion dark UI language.
   NOTE: Class names are unchanged from the previous stylesheet so that no
   HTML, JS, or content had to be touched on 100+ pages — this is a visual
   redesign that every page inherits automatically.
