   N! Base Theme — Estilos principais
   Organização: 1) Reset/base 2) Variáveis 3) Tipografia 4) Layout/Grid
   5) Acessibilidade 6) Componentes 7) Utilitários 8) Responsivo.
   Sem dependência de frameworks (Bootstrap/Tailwind). Esta é uma base
   deliberadamente enxuta — cada projeto adiciona seus próprios componentes
   (heros, banners, grades, etc.) por cima destes fundamentos.
