/*
 * KAC wp-login.php skin.
 *
 * Mirrors frontend/src/app/login/page.tsx as a near-clone:
 *   - Split-screen 580px navy panel (left) / white form (right)
 *   - Navy gradient background with a faint gold radial wash
 *   - KAC logo replaces the WordPress mark
 *   - "Powered by WordPress" footer is hidden
 *
 * Tokens are loaded by tokens.css (enqueued on login_enqueue_scripts
 * before this file). All colors below are var(--kac-*) so a single
 * token change ripples to login + admin + frontend.
