/* ==========================================================================
   AUTH SPLIT — Layout "metade imagem | metade formulário" em todas as telas
   de autenticação (login, cadastro, admin, parceiro, senha, confirmar).
   - Desktop >= 1024px: metade esquerda imagem presa à viewport (sticky) —
     nunca estica quando o formulário é mais alto que a tela (ex.: cadastro).
   - Mobile: imagem como fundo imersivo desfocado atrás do card.
   - Sem logos: apenas o formulário à direita e o link "← Voltar ao site".
   As imagens vivem em /imagens/auth/<pagina>.jpg, com fallback para login.jpg
   e, por fim, para o gradiente navy da marca.
   ========================================================================== */

/* ---------- Mobile-first: imagem como fundo imersivo ---------- */
/* No mobile a imagem fica NÍTIDA (sem blur), cobrindo 100% da tela; o
   efeito de vidro fosco fica no CARD (backdrop-filter), que "reflete"
   levemente a imagem atrás. */
