   WITCODE — magic-ui.css
   Efectos interactivos inspirados en componentes gratuitos de Magic UI
   (magicui.design, licencia MIT), recreados en CSS puro para el sitio
   estático (sin React / Tailwind / Motion). Se carga en index.html y en
   diagnostico-gasto-ia.html (landing Design Partners, desde 22/10/2026;
   ver bloque "Variantes para diagnostico-gasto-ia.html" más abajo).

   Intensidad: SUTIL (decisión del usuario, 22/10/2026).

   Componentes recreados (nombre Magic UI → clase local):
     - Shimmer Button           → .mu-shimmer        (botón "Comunidad Witcode" del hero)
     - Animated Gradient Text   → .hero h1 em        ("A Negocios" del hero)
     - Magic Card (spotlight)   → .mu-spotlight      (tarjetas de Servicios)
     - Border Beam              → .mu-beam           (imágenes de Novedades + recuadro FAQ)
     - Dot Pattern              → .mu-dots           (secciones oscuras)
     - Meteors                  → .mu-meteors        ("¿Qué hacemos?")
     - Ripple                   → .mu-ripple         (ícono de contacto)
     - Confetti                 → JS (magic-ui.js)   (al copiar el mail)

   Todo respeta prefers-reduced-motion (ver bloque final).
