/**
 * KS Explorer SSO — Login Form Styles
 *
 * This stylesheet extends the existing explorer-login.css from the
 * Kansas Attractions plugin. It reuses the same `.explorer-login-form`
 * class hierarchy and Kansas Guidebook brand variables so both login
 * shortcodes look identical.
 *
 * Only SSO-specific additions (password toggle, membership badge) are
 * defined here. The base card, form fields, buttons, messages, footer,
 * and responsive rules come from the existing explorer-login.css.
 *
 * @package KSExplorerSSO
 * @version 1.0.0
