/* =============================================================
   auth.css — Sistema visual premium das telas de auth público
   Sprint 5.1 (revisado 28/Abr/2026 noite)

   Aplicado em: painel (login), esqueci_senha, novasenha, confirm_email.

   Layout:
   - Mobile (<1024px): card centralizado com sombra, fundo cinza claro
   - Desktop (>=1024px): split layout — painel preto à esquerda
     (logo branca + texto institucional + créditos), form à direita
     em fundo branco

   FIX bug Sprint 5.1 v1: tokens light fixos dentro de .auth-page para
   ignorar dark theme global default. Inputs ficaram invisíveis porque
   --color-border default (rgba branca) não contrastava com fundo branco.
