   Este bloco só afeta telas abaixo do breakpoint que o próprio sistema já
   usa como corte mobile/desktop (.section e .container já mudam de escala

   de espaçamento/tipografia grandes (--sp-5 a --sp-8, --fs-3xl/4xl), que já
   alimentam dezenas de componentes (cards, seções, hero, depoimentos, FAQ,
   rodapé) — assim uma mudança pequena reduz a altura da página inteira sem
   duplicar regras por componente. O que não é resolvido por token (ícones e
   números com tamanho fixo em px) recebe um ajuste pontual abaixo.
