/**
 * 工作区统一布局（聊天同款：左侧菜单 + 右侧内容）
 * 用于：收藏、网盘，以及后续同类页面
 *
 * 资源约定（性能）：
 * - 页面走 layout/center 的 IM 轻量模式（meta_im + require-im）
 * - 只用 bootstrap / font-awesome / layer / 本文件 + favorite.css
 * - 不要再引入 frontend.min.css、moment、bootstrap-table 等后台大包
 *
 * 结构约定：
 * <div class="ws-app" id="...">
 *   <aside class="ws-side">...</aside>
 *   <section class="ws-main">
 *     <div class="ws-toolbar">...</div>
 *     <div class="ws-body">...</div>
 *   </section>
 * </div>
