 * popups.css — 文章页订阅弹窗样式 (v20260928a)
 *
 * 配套：layouts/_partials/popups/popup-engine.html
 *      layouts/_partials/popups/popups/subscribe_random.html
 *      static/js/popup-engine.js
 *
 * 设计原则：
 *   - 与现有 .mlwm-auth-modal / .mlwm-denied-modal 同根（浅色卡 + 圆角 + 软阴影）
 *   - 视觉重音：绿色主调 (#22c55e) + 礼物/新用户徽章 + 4 特性 + 大 CTA
 *   - 移动端：max-width 100%，features 改 2 列，关闭按钮加 hit area
