/* ==================================================================
 * 挖矿软件管理 — 右侧贴边快速跳转图标条
 *
 * 范围：仅 /mining-software/（归档与 ms_* 分类归档）和软件详情页。
 * 形态：
 *   桌面（>=1450px）默认展开：右缘常驻一列图标，悬停浮出名称气泡，点击跳转。
 *   窄屏（<1450px）默认收起：右缘只留一个窄把手，点击展开 / 再点收起。
 * 无 JS 时：面板保持展开（渐进增强，不会出现「打不开」的死状态）；
 *          名称气泡由 JS 驱动，无 JS 时靠链接自身可访问名兜底。
 *
 * 布局要点：本容器 height:100% + align-items:center 实现垂直居中，
 * 刻意不使用 transform —— 这样内部的 position:fixed 气泡以视口为参照，
 * rail.js 可以直接用 getBoundingClientRect() 的坐标定位，不需要换算。
