/* ==========================================================================
   PBNC — AI-powered education & skill development
   style.css

   Architecture
     1  Brand constants        — never change with theme
     2  Semantic tokens        — light (:root) / dark (html[data-theme="dark"])
     3  Feature-dark scope     — .on-dark remaps the semantic tokens for the
                                 deep-navy environments (hero, AI-GOS, quiz,
                                 contact, footer, dark panels, mobile menu)
     4  Theme-switch fade
     5  Base + the continuous ground
     6  Surface bands & light/dark ramps
     7+ Components & sections
     24 Reduced motion

   Components never hardcode a theme colour: they consume var(--surface),
   var(--text), var(--border)… and therefore adapt automatically in light
   mode, dark mode and inside dark feature environments.
   (breakpoint overrides live in responsive.css)
