     Roboto, sans-serif (títulos e corpo). Código: ui-monospace,

   - Escala (tamanho/altura de linha em px): H1 30/36 peso 600
     letter-spacing -0.4px; H2 24/30 peso 600; H3 20/26 peso 500;
     corpo 16/24 peso 400; legendas 14/20 e 12/16 (meta, breadcrumb,
     notas, rodapé); tabelas 15/22. Negrito (strong, b, botões,
     títulos de cartão, summary do FAQ) sempre peso 600, nunca
     700/800. Coluna de conteúdo max-width 700px.
   - Cores: fundo #FFFFFF (superfícies claras ok, ex. #F6F8F7), texto
     #0A0A0B; barra do topo e CTA (botões e caixa) com fundo #39CFB2 e
     texto #0A0A0B, hover #2AA18D; links sublinhados em #1E7A6B
     (teal escurecido de #2AA18D para contraste 5,18:1 no branco),
     hover #2AA18D sublinhado; caixa de regras/destaque (blockquote)
     com fundo #E8F8F5 (tom claro de #8EE0D4), texto #0A0A0B, borda
     #8EE0D4; #F5A524 reservado para a linha de teto do simulador (no
     máximo um destaque — o aviso de "post de exemplo"); negativo em
     preenchimento #FF7A8A, texto pequeno negativo #C8323F (5,27:1);
     positivo em preenchimento #3DD68C, texto #1A7F4E. Nunca texto
