/* =========================================================================
   SPARX — tema partilhado (claro + escuro) para outros sites internos.
   Extraído de sparx-ui.css (SPARX, versão ?v=20261015a) sem os seletores
   específicos das páginas de faturas. Usa os mesmos tokens (--sx-*), por isso
   os valores podem ser sincronizados com o SPARX copiando os dois blocos :root.

   Precisa de: sparx-tema.js no <head> (antes deste CSS ou logo a seguir) e da
   letra Roboto (Google Fonts ou ficheiros locais). Não depende do Bootstrap.
