/* =========================================================================
   TTM SITE NEXT — design system
   Traditional-website redesign of totaltalentmindset.com (sandbox build).

   Conventions every page follows (set here, copied everywhere):
   - Tokens live on :root; themes switch on html[data-theme="dark"|"light"].
   - Layout: .wrap (max 1180px, fluid gutters) inside .band sections.
   - Type: .display (H1), .h2, .eyebrow, .lede, .grad-text (brand signature).
   - Components: .btn / .btn-primary / .btn-ghost,
     .card (with --accent), .panel, .site-nav, .site-foot,
     .phase-arc, .stats-trio, .vs-table, .closing-scene, [data-reveal] motion.
   - Mona Sans only. Brand colors only. Dark first; light fully designed.
