/* ui/home.c — 我的歌单页（ACT_HOME，根页）。
|
||||
*
|
||||
* 内容区用 SDK 结构化列表（meow_listview，§5.5 W_LISTVIEW）虚拟化渲染
|
||||
* 「图标(folder 占位) + 歌单名 + 曲目数副标题 + 右侧箭头」。行数据源逐行填 meow_list_item；
|
||||
* 滚动/选中/命中由 SDK 收口。空态/错误/底部信息行用 meow_draw_custom_register 注册非控件绘制物。
|
||||
* 左缘返回 = 退出 App（app.c 处理）。下拉刷新可选：用 topbar 「↻」 动作项。
