/*!
 * ms-share.css — 文章分享 & 收藏皮肤（v2 · 2026-09-26）
 *
 * 渠道图标由开源 Share.js / social-share.js 1.0.16 引擎渲染（iconfont），
 * 本文件只做「工业简约 + 深底」皮肤：不引第三方 CSS，避免它的默认白底浮层与
 * `top:-205px` 二维码定位（在正文里会被祖先 overflow 裁掉）。
 *
 * 交互（用户要求）：正文末尾只有一个分享图标 → 点击弹出面板 → 面板里是几个渠道。
 * 二维码视图在面板内部切换（面板是 fixed 定位，绝不依赖祖先 overflow）。
