/* static/css/login.css - Login do App (PWA) - redesign 22/09/2026
 *
 * - Celular (até 599px): layout de app nativo em tela cheia. Topo azul com a
 *   logo e, por baixo, uma "folha" branca com cantos arredondados que ocupa o
 *   resto da tela (sem cartão flutuando com margens sobrando).
 * - Telas maiores: cartão centralizado, como antes, com acabamento refinado.
 * - Modal de alerta (Problemas no acesso): bottom sheet no celular, diálogo
 *   centralizado em telas maiores.
