/* ui/queue.c — 当前实时播放队列页（ACT_QUEUE，§NEW：播放页「队列」钮进入）。
|
||
*
|
||
* 展示**当前播放队列**（player_manager 的 queue_src —— 歌单滑动窗口 或 搜索单曲结果集），
|
||
* 含当前曲高亮、可点某行切到那首播放。数据源与分页复用歌单滑动窗口（REPORT §17）：
|
||
* - count = appstate_queue_count()（全量：track_ids_count 或 search_song_count，可 5194 首）；
|
||
* - 行内容 = src2 逐行按 queue_src 取（PLAYLIST→滑窗拷贝，SEARCH→搜索数组），未物化槽显示
|
||
* ".../加载中" 占位，视口 ±24 行未物化 → 后台 worker ensure_range 补载（盘缓存优先，批≤NCM_SONG_BATCH）；
|
||
* - 列表本身由 meow_listview 虚拟化（只画视口内行），不整歌单常驻内存 → 任意长度不卡死。
|
||
* - SEARCH 队列行全在内存（≤256），无需 ensure；PLAYLIST 队列走滑窗+ensure（含网络）。
|
||
* 当前曲高亮 = 播放页三态钮旁队列页以红色左条 + 红色轻染标记 player_manager_playing_song()
|
||
* 所在行（queue idx 与播放队列下标一致，两种 queue_src 通用）。
|
||
*
|
||
* 布局（无封面头块，纯列表）：topbar「播放列表」+ 曲目列表 + 底部 `first-last / N 首` 页脚。
|
||
* 左缘返回 = 弹回上一页（播放页，app.c）；点击行 → player_play_queue_song（保持当前 queue_src）。
