/**

* 返回所有 Element Plus 组件的样式入口（style/index + style/css）。
|
|
|
*
|
|
|
* 这些路径路由懒加载组件首次渲染时若未预热，vite optimizer 会重新处理
|
|
|
* → "new dependencies optimized → reloading" 循环，导致菜单切换卡顿 + 整页刷新。
|
|
|
* 提前加入 optimizeDeps.include 可消除此问题（仅影响 dev 启动预编译，不影响生产）。
|
|
|
*
|
|
|
* - style/css：预编译 CSS（兜底）
|
|
|
* - style/index：SCSS 入口。useSource: true 时必须预热，否则懒加载触发 optimizer。
|
|
|
*
|
|
|
* 性能权衡
|
|
|
* --------
|
|
|
* - 当前实现：一次性预热 ~244 个 EP 路径（122 个组件 × 2 入口），dev 启动慢 1-2 分钟
|
|
|
* 但后续路由切换零卡顿。
|
|
|
* - 未来优化：扫描 src/ 中实际用到的 el-xxx 组件名，只预热这部分。
|
|
|
* 实测本项目用到了约 70 个不同 EP 组件，可减少 40%+ 预热开销。
|
|
|
* 需在新增 EP 组件时同步更新扫描结果，否则会再次触发菜单卡顿。
