   Organização:
     1. Design tokens (variáveis CSS — única fonte de verdade visual)
     2. Reset / base
     3. Tipografia
     4. Layout utilitário (.container)
     5. Componentes (nav, botões, hero, processo, galeria, etc.)
     6. Animações / reveal on scroll
     7. Acessibilidade (prefers-reduced-motion)

   Notas de desempenho:
     - `will-change` apenas em elementos que realmente animam (evitar
       criar camadas de composição desnecessárias).
     - Transições com cubic-bezier(--ease) personalizado para suavidade.
     - `backdrop-filter` prefixado para Safari.
     - `content-visibility` poderia ser usado em secções abaixo da fold,
       mas omitido aqui para manter consistência cross-browser.
