/*
 * Tela de autenticação do IdP.
 *
 * Porte da tela de login do Hub de Valor, para que entrar na plataforma e
 * entrar no IdP sejam visualmente a mesma coisa. Os valores vêm dos tokens do
 * front (globals.css, escopo `dark`) e da paleta `graphite` do Tailwind —
 * copiados, não importados: o IdP não tem build de CSS e não deve depender do
 * pipeline do front para renderizar a própria tela.
 *
 * Sem JavaScript, por construção: a CSP destas páginas é `default-src 'none'`
 * sem `script-src`. Por isso não há revelar-senha nem animação de biblioteca —
 * o movimento é `@keyframes`, e os ícones são SVG inline (marcação, não `img`,
 * então passam por `img-src` sem precisar de arquivo).
