/* ===== styles-im-ctx.css — 聊天消息右键菜单（PC 端，2026-09-16）=====
   设计取向：**不复刻微信**。微信右键菜单是「浅灰底 + 直角 + 上下分隔线 + emoji 图标」；
   本菜单走「深色玻璃质感（glassmorphism）+ 圆角卡片 + 左侧线性 SVG 图标 + 悬停蓝色高亮」，
   与全站品牌蓝 #2563eb 一致，图标全部为自研 SVG（见 styles-icons.css 的 ico-copy / ico-quote /
   ico-forward / ico-multiselect / ico-delete / ico-recall），零 emoji、零第三方素材。
   关闭方式：点击空白处 / ESC / 滚动 / 窗口失焦。置灰项不可点击并给出原因 tooltip（title）。 */
