/* ---- Design personalizado: hadith.com.br -----------------------------
   Paleta: tinta índigo (manuscritos iluminados / "Alcorão Azul"),
   papel-pedra (pergaminho neutro, não creme-terracota padrão),
   rubrica em vermelho-oxblood (títulos de seção em manuscritos antigos)
   e traço em latão para regras finas.
   Tipografia: Amiri (árabe, mesma da Quran impressa) + Lora (serifada,
   leitura longa em PT/EN) + Inter só para controles de interface.

   Modo noturno: mesma identidade, tons invertidos — pergaminho vira
   tinta quase-preta, tinta índigo vira texto claro. Ativado via
   [data-bs-theme="dark"] no ancestor (mesmo mecanismo do Bootstrap 5.3).
