/* taskbar.c — Win11 Fluent 居中悬浮任务栏 + 系统托盘（M2）
 *
 * 布局（深色主题 g_wf_dark）：
 *   主任务栏：48px 高，距底 8px，水平居中悬浮，acrylic 圆角 12
 *     [开始 40×40] [任务视图 40×40] [运行窗口按钮 44×44 ...]
 *     运行中 = 底部 3×16 accent 指示条；聚焦 = 指示条加宽 6px + 微亮蒙层
 *   托盘组（右下角独立悬浮，同视觉）：
 *     [网络 40] [音量 40] [电源 40] [两行时钟：HH:MM / M-D]
 *
 * 点击路由 taskbar_click() 由 shell.c 在 Fluent 分支调用。
 * 开始菜单 M3 接入；电源 M2 直接退出（M7 扩展菜单）。
