   Origem: skill `design-system` (~/.claude/skills/design-system/assets/).
   Num projeto, isto é uma CÓPIA: não edite; mude na skill e copie de novo.
   Camada de ESTRUTURA: não muda entre produtos. Só lê tokens (tokens.css);
   nenhum hex aqui, exceto branco/preto de brilho especular.

   Camadas de cascata compatíveis com Tailwind v4: base e componentes ficam
   em @layer, então um utilitário no markup (mt-2, w-full, px-6) sempre
   vence o componente — sem !important.
