   Paleta v3 do Manual de Marca: verde petróleo profundo #1F3D3A e old gold
   #CFA94F, com off-white quente #FAF8F2. Playfair Display nos títulos e
   Inter no texto. CSS puro, sem build.

   Direção escura: o fundo é um verde petróleo quase preto, derivado do
   #1F3D3A, para a fotografia de obra ter profundidade. O dourado fica em
   acento (rótulo, filete, botão), dentro da regra de 10% do manual.
