   Golden AI — site institucional
   HTML5 + CSS3 vanilla. Sem frameworks.

   Direção (set/2026): as regras do Liquid Glass da Apple (HIG · Materials,
   Buttons, Toolbars, Layout, Color, Motion) traduzidas para a web.
   A regra que organiza o arquivo inteiro:
     · camada de CONTROLE (cápsula de navegação, menu, dock, controles do
       aparelho) = vidro que flutua, refrata e responde ao toque;
     · camada de CONTEÚDO (texto, tabela, cases, FAQ, fundadores) = sem vidro,
       sem caixa. A hierarquia vem de tipografia, espaço e linha fina.
