/* ============================================================
 * 资源下载板块 —— 页面样式（公开下载页 + 管理控制台共用）
 *
 * 依赖 flasher/css/flasher.css：导航、布局骨架（.dashboard/.sidebar/.content-area）、
 * 登录浮层、按钮（.btn-sm/.btn-primary/.btn-outline/.btn-danger）、提示条（.toast）、
 * 弹窗（.modal/…）都在那边；这里只做本板块的「皮肤」：
 *   目录树（含备注副标题/拖放反馈）、工具条与面包屑、卡片化的文件与目录、拖拽落区、
 *   控制台的区块/表单/限速面板。
 *
 * 配色约定：
 *   · 语义色来自主题变量（--primary/--card-bg/--border/--text…），跟随深/浅色主题；
 *   · 「类型色调」用本文件里的 --tone-fg/--tone-bg 自定义属性成对出现（图标底 + 图标色），
 *     由 JS 加 dl-tone-* 类（见 _site/js/dl-ui.js 的 toneClass）；
 *   · 圆角/描边/阴影走 --dl-* 令牌，改一处即整页统一。
