   VESTBJØRN · Magic UI-laget (MIT, magicui.design), portert til rein CSS/JS
   utan React/Tailwind. Same mekanikk som originalkomponentane, tilpassa
   «Djupgangen»: lysblå på navy, skrå kutt, mono-merking.
   Komponentar: Marquee, AnimatedShinyText, BlurFade, BorderBeam,
   AnimatedBeam, Ripple (som ekkolodd), AnimatedGridPattern (sjøkartrute),
   NumberTicker (main.js), ShimmerButton, og strektegning av GA-teikninga.
   Alt står stille ved prefers-reduced-motion.
