/* ════════════════════════════════════════════════════════════════
   KELECHI ONUOHA — PORTFOLIO v3 "STOREFRONT"
   Concept: the portfolio behaves like a premium DTC storefront,
   because that's the product Kelechi sells. Light, retail-grade,
   conversion-first.

   Tokens → base → components → sections → pages → responsive
