/* ══════════════════════════════════════════════════════════════════════════
   chrome-a.css — header, menu mobile e rodapé IDÊNTICOS às páginas atuais
   do site (design A). Extraído de contact.html/index.html com valores
   literais (self-contained), para não colidir com tokens/base/components.

   Carregado por ÚLTIMO nas 5 páginas novas → vence as regras do design B.
   Dropdowns usam .is-open (a classe que o ui.js alterna), então o ui.js
   dirige a abertura sem precisar de JS extra.
