   ZMILE ART — DESIGN SYSTEM (NEBULA DS 05)
   Fonte única de verdade visual de todo o produto Zmile Art.
   Portado de "Landing Page Design System 05" (origem de zmile-cursos.com.br),
   tornado self-contained (sem dependências locais externas).

   Camadas:
   - Tokens (cores, tipografia, easings)
   - Sistema de fundo (aura líquida, beams, fog, orb, noise, dots, gradient-blur)
   - Navbar glass
   - Botões (button-custom, btn-beam, shiny-cta, btn-ghost, btn-nav-accent)
   - Cards (project-card 3D tilt, flashlight, card-3d, glass-panel, testimonial)
   - Timeline vertical, CTA final, inputs, tooltip, modal, ícones
   - Utilitários de animação de entrada

   REGRA SAGRADA DA MISSÃO: esta folha altera SOMENTE a aparência. Nunca
   conteúdo nem funcionalidade. Não aplicar às áreas de preview do conteúdo
   do usuário (marca do cliente — DS#2).
