/* ============================================================================
   Oprenna — identidade visual das paginas de autenticacao.

   Fonte unica de tokens e componentes de app/templates/auth/*.html (via
   auth/_layout.html). Isolada de proposito do main.css (nao unificar ainda):
   tokens --oa-* e classes oa-* nao colidem com o painel. Os VALORES seguem a
   mesma identidade do main.css (navy + azul eletrico): --oa-primary = fill com
   texto branco (4,6:1), --oa-accent = texto/borda/foco. Ao mudar a paleta do
   painel, mantenha estes valores alinhados (tests/test_no_literal_colors.py
   compara os principais).

   Nao ha regra de negocio aqui — apenas apresentacao.
