/* ==========================================================================
   Tela de login/cadastro — layout dividido do modelo AK Gestor.html.
   Página própria (login.php/cadastro.php não passam pelo index.php), por
   isso carrega separadamente. Consome os tokens de custom.css e reusa os
   componentes de ak-components.css (que são escopados em .ak-page — a
   página de auth também usa esse wrapper só pra reaproveitar o CSS).
