   dock.css —— Dock 化侧栏 + 移动端左滑抽屉（第 1 项改造）
   直写编译产物（主题 webpack 链损坏，node_modules 缺失；源镜像见 source-src/css/dock.scss）
   视觉真源：/Users/fcc/mini1/designs/blog-modernization/index.html
   规则：
   - html[data-dock="expanded"|"collapsed"]（dock.js 维护，localStorage yilia.dock）
   - html[data-drawer="open"|"closed"]（移动抽屉，dock.js 维护）
   - 断点沿用主题既有 800px（设计稿 768px 统一上移，避免夹缝断裂）
   - 展开态 width 300px ↔ 收起态 64px；hero 180px ↔ 52px；曲线 .25s cubic-bezier(.42,0,.58,1)

/* ---------- 第五波：滑出面板接入 Dock 收缩几何 ----------
   病根：面板/正文开合走 bounce keyframe——.tools-col.show 的 smallLeftIn
   终点 translate3d(300px)（fill both 常驻），.mid-col.show 的 leftIn 终点
   translate3d(333px)。transform 优先级高于 left：收缩态仅把 left 改 64px
   会被动画终点再叠 300px，面板实际落 x≈364 压住正文；正文让位动画也按
   展开态 300px 侧栏写死，与 64px Dock 几何错位。关闭态还有离场动画
   （.tools-col.hide 的 smallleftOut / .mid-col.hide 的 leftOut）。
   修法（仅桌面 ≥801px；≤800px 移动端走独立 m-drawer 抽屉，data-dock 不
   影响其布局，本块不生效）：
   - 收起态弃用面板/正文四条 keyframe，改 left+opacity 过渡驱动（面板
     复用 .tools-col 基态已有 transition 思路，正文沿用上方 :114 的
     left .25s 过渡）；
   - 面板左缘贴 64px 图标栏右缘：开(.show)/关(.tools-col)/离场(.hide)
     三态同 left，不再被动画拖去 300/364px；
   - 正文让位 left 64→397px（= 64 + 展开态同款 333px 让位量）。面板内容
     右缘 64+20+310=394 < 397，正文零遮挡，比例复刻展开态 600↔633 的
     33px 间隙；
   - 打开后面板左缘 64px 处与图标栏无缝衔接，dock-handle(x∈[52,76])
     仍在上层可点。 */
