   Séries de dados: gasolina #7A8E14 · álcool #0C96B3

   Camadas:
   1. Tokens          — variáveis de escala (cor, tipo, espaço, raio, sombra, z, motion)
   2. Base            — reset, corpo, superfícies do navegador
   3. Layout          — topbar, coluna do app, tabbar
   4. Componentes     — cada padrão de UI nomeado, só consome tokens
   5. Utilitários     — espaçamento e texto mínimos
   6. Motion          — entradas, reduced-motion
