/* ui/browser.c — 目录浏览页（ACT_BROWSER，根页）view + 控制器。
|
||
*
|
||
* 职责：
|
||
* - 持有目录态（g_cur 当前目录 / g_entries 缓存快照 / g_err 空态码）；
|
||
* - 内容区用 SDK 结构化列表（meow_listview，§5.5 W_LISTVIEW）虚拟化渲染
|
||
* 「图标 + 名称 + 大小/时间 + 右侧 ⋯ 操作钮」行：行数据源 browser_src2 逐行填充
|
||
* meow_list_item（icon_kind=目录/文件符号、副标题=大小/时间、right=⋯）。滚动/选中命中由
|
||
* SDK 收口（视口裁剪、局部 dirty、disabled 不响应），App 只在 on_tap/touch_move 驱动
|
||
* scroll/sel 并分发：行体=进目录/开预览；右侧 ⋯ 或长按 → BottomSheet（删除/重命名/新建/属性）；
|
||
* - 空态/错误（无卡/空目录/权限）与底部信息行用 meow_draw_custom_register 注册为非控件绘制物
|
||
* （app_draw_empty / app_draw_footer）——列表视口不含页脚，行不压页脚；invalidate/paint_full
|
||
* 自动重画它们；
|
||
* - 写操作只经 logic（fsx_*），且在卡内校验后执行。
|
||
*
|
||
* 颜色全部读 meow_theme_get() 语义色（§8.1），不硬编码。
