/* =========================================================
   Kruti Jadav — Portfolio
   Concept: "schema-first" — the site is staged like a system
   architecture diagram. A fixed blueprint grid + drifting
   gradient glow sit behind everything; the hero's layered
   stack graphic is blown up and annotated like a real schema.
   One accent trio (violet / teal / pink) tied to the three
   layers of the stack, spent boldly in the hero and sparingly
   everywhere else.
