   Complexsys Design System
   Brand: azul Complexsys #003AA8 + preto (logo). Tudo deriva dessas duas cores.

   Estrutura
   1. Tokens primitivos (paleta, tipografia, espaço, raio, sombra, movimento)
   2. Tokens semânticos (contexto claro por padrão, .theme-dark inverte)
   3. Base, tipografia, layout
   4. Componentes (botões, badges, cards, bento, formulários...)
   5. Seções e páginas
   6. Movimento (reveal, spotlight, view transitions) + reduced motion
