/* Site institucional — folha própria, separada de assets/style.css (compartilhado com
   toda a área restrita/admin). Redesign 2026-08-30: tema claro, inspirado na estrutura
   visual de referências do setor (Inter, botões em pílula, muito espaço em branco,
   um único acento confiante) — cor de acento é o azul índigo que já é da marca
   CyberHervor (mesmo primary-600 do dashboard do produto, tailwind.config.js), não uma
   cópia de paleta de concorrente. */
