/*
 * Login page styles (login-with-google.php / login.php).
 *
 * Theme resolution matches modern Tourbot + user.php:
 *   - default / data-theme="light"  -> light
 *   - data-theme="dark"             -> dark (forced)
 *   - system dark + no data-theme   -> dark via prefers-color-scheme (the
 *     no-JS fallback; with JS the toggle always sets data-theme explicitly)
 *
 * A page-local three-state toggle stores light|dark|system in localStorage
 * (login.php-theme) and mirrors the choice onto data-theme-pref, which is what
 * the button's icon keys off. data-theme always carries the *resolved* scheme.
