   MUDANÇAS DESTA REVISÃO (v6):
   · Fundo off-white quente (estilo Lovable) mantendo violeta + dourado
   · Hero: mandala circular removida → auras de cor desfocadas (blur)
   · Nav em vidro fosco (glassmorphism leve) nos dois modos
   · CTAs e botões principais em pill; cards com raio maior e sombra suave
   · Emojis de áreas substituídos por ícones SVG de linha
   · Dark mode refinado (near-black quente), contraste AA mantido
   ─────────────────────────────────────────────────────────────────────────
   ESTRUTURA:
   1. Reset e base
   2. Tokens modo claro (:root)
   3. Tokens modo escuro (
