/* ==========================================================================
   NOVISEC — Novi Security Systems
   Design system with DUAL THEME (dark default + light)
   Colors are RGB channel triplets in CSS vars so Tailwind utilities
   (mapped to rgb(var(--c-x) / <alpha-value>)) and component CSS both theme.
   The accent ("gold") becomes blue in light mode.
   Type: Clash Display (headlines) + Satoshi (body)
   Motion: hand-crafted easing, JS is enhancement only.
