/* ASO app (produto) — redesenho "Eixo Frio". UTF-8, responsivo, zero dependências externas.
   Tese: a interface traduz a constituição — contenção, testemunho, silêncio.

   a do utilizador em sans; a evidência documental em mono. Uma só cor de acento fria (aço) para
   o ASO; âmbar contido para o Cândido. Tema único "Tinta" (escuro frio, texto papel-quente). */
