/*
 * Identidade do G10 para o site do Gabinete de IA.
 * Tirada da prévia aprovada da página de acesso (docs/assessor-ia/previas/academy-entrar do repositório do kit)
 * e da landing do G10 (src/components/landing/landing.css, lead-g10.css, Seda.tsx, tema.tsx): nada inventado.
 *
 * Sem estilo inline nas páginas: a CSP não deixa. Atraso e estado vão por classe.
 * Ícones: as páginas ligam o CSS do Material Symbols (só fonte, sem script), com a lista de nomes que usam, por exemplo
 *   https://fonts.googleapis.com/css2?family=Material+Symbols+Outlined:opsz,wght,FILL,GRAD@24,400,0,0&icon_names=dark_mode,light_mode&display=block
 * Fontes de texto: Schibsted Grotesk e Libre Caslon Text (itálico), pelo Google Fonts.
 *
 * Moldes de HTML:
 *   barra   <header class="bar glass"><a class="logo" href="/">Gabinete de <em>IA</em></a>
 *           <div class="acts"><button class="theme-btn" type="button" aria-pressed="false" aria-label="Mudar para o modo escuro" title="Modo escuro">
 *           <span class="ms moon" aria-hidden="true">dark_mode</span><span class="ms sun" aria-hidden="true">light_mode</span></button></div></header>
