/* ==========================================================================
   Spell UI → VPay (porte para CSS/JS puro)
   Fonte: registro shadcn do Spell UI, https://spell.sh/r/{nome}.json
   (o mesmo que o MCP de https://spell.sh/docs/mcp entrega ao editor).
   O site é HTML estático, então os componentes React/motion foram portados:
     texto      → blur-reveal, words-stagger, shimmer-text, highlighted-text,
                  gradient-wave-text
     movimento  → marquee, logos-carousel, tilt-card (com spotlight)
     botões     → rich-button, flow-button, pop-button, copy-button
     fundo      → light-rays (aproximação em CSS; o original usa three.js)
   Tudo respeita prefers-reduced-motion (regra global do site).
