/* tokens.css — Grade Point Solutions design system
   Concept: "Vertex" — client-requested reskin. Dark, near-black warm
   charcoal-navy is now the PRIMARY default theme (confident, modern SaaS-
   launch energy), with a vivid sky-blue accent doing the heavy lifting on
   CTAs, headline highlight words, eyebrows, and hover states. A teal/cyan
   secondary accent is reserved for badges and small labels. Light mode is
   preserved as an explicit toggle, not the default. */
