/* ---------- 登录页 ----------
 * 交付目标是「客户演示第一屏」：一屏之内点得到全部演示身份，字要看得清。
 * 因此这里有一组硬约束，改动前请先读：
 * 1) .login 固定 100dvh + overflow:hidden —— 页面本身永远不出滚动条；
 *    内容确实放不下时，只允许右下面板的 .panel__grid 内部滚动，不会把身份卡顶出屏幕。
 * 2) 面板是浅色底（rgba(255,255,255,.98)），所以面板内的文字一律用深色，
 *    不要再出现 rgba(255,255,255,*) 这类「深色底才用」的颜色（历史上就是这么糊掉的）。
 * 3) 字号下限：正文 12.5px、按钮名 13.5px，颜色对比度 ≥ 4.5:1。
