/**
 * XQBase — giao diện card đăng nhập, dùng CHUNG cho:
 *   - trang view=login  (bọc trong .xq-lg-stage, nền gradient)
 *   - popup ở explorer  (card trần trong .xq-modal)
 *
 * ⚠ CỐ Ý KHÔNG scope theo wrapper (.xqbase-login/.xqbase-explorer) và KHÔNG dùng
 * var(--xq-blue): modal có thể bị portal ra document.body, khi đó cả scope lẫn
 * biến CSS đều mất sạch (MEMORY: đã dính 3 lần — v2.8.2, v2.9.0, v2.18.2).
 * Mọi màu hardcode; prefix .xq-lg-* đủ hẹp để không đụng ai.
