真机（0.8.48 / reader 0.1.1 基线，同机同字库 ztest 实测）： - 从阅读页返回书架：3435ms（3259–3531）→ 33ms（24–54）。根因是 shelf_on_enter 无条件 scan_books()：exFAT 全量扫描 434 目录 = 3.1s。改为进程内缓存（首次进入才扫，顶栏 「刷新」强制重扫）；truncated/depth_skipped 提示语义不变（首次扫描时算好并保留）。 行为变化：新进 Books/ 的书、刚读完那本书的「最近阅读置顶」需点一次「刷新」才更新。 - 书架滑动每步（62px，含 widget_draw + flush）：51.9–56.2ms → 19.3–19.9ms。 行数 > 200 时 meow_listview_set_container(0)（扁平行），≤200 行仍用 MD3 圆角卡； 圆角卡走 meow_gfx_fill_round 逐像素 rr_inside（464×54 一张 3.8–6.4ms ×11 行）。 - 首次进书架仍需扫一次（3497ms，含 3157ms 扫描）；595 本全可见、format/folder 分组不变。 另加 test/shelf_bench_ondev.c（真机耗时基准，不进 mpk）与 build_reader.sh 的编译步骤； app.json 0.1.1/2 → 0.1.2/3。未做（按塔砍范围）：字体路径记忆化、首屏只渲染当前页、 自绘行、mtime 失效检测。

/* app/shelf.c — 书架：扫 TF 卡 `Books/`，识别 TXT/FB2/EPUB/MOBI/CBZ（R1 仅 TXT 可开，
|
||
* 其它显示「R2 支持」占位）；MD3 布局（meow_topappbar + list/grid）+ 最近阅读置顶 + 段头分组。
|
||
*
|
||
* 布局（README §3.2，用户 2026-09-04 拍板）：
|
||
* - 默认 list（meow_listview_set_container(on) MD3 圆角卡；**行数 > SHELF_ROUND_MAX_ROWS
|
||
* 时自动降级为扁平行**——圆角卡逐像素填充太慢，见 shelf_build_content 注释），
|
||
* 可切 grid（meow_lazygrid 4 列封面卡）；布局存 reader.conf `ui.shelf_layout`；
|
||
* - 顶栏 meow_topappbar：标题「书架」+ 动作（布局切换 / 分组切换 / 刷新 / App 设置入口）；
|
||
* - 无书也渲染完整骨架（顶栏 + 内容区 + 居中空态卡 + 指引 + 支持格式）；
|
||
* - 封面：MVP 无封面提取（engine F1）；无则圆角占位（surfaceContainerHigh + 格式徽标）。
|
||
*
|
||
* M27 分组（`ui.shelf_group`，默认 format 保持旧行为）：
|
||
* format = 按格式分段（TXT/FB2/EPUB/MOBI/CBZ）；
|
||
* folder = 按 Books/ 下的「第一级目录」分段（根下=未分类），更深子路径（分类/作品）进副题。
|
||
* 扫描/行序列在 app/shelf_model.c（纯 C，宿主可测）；本文件只做控件装配与绘制。
|
||
*
|
||
* M29 性能（用户反馈「几百本书首页卡得飞起」）：
|
||
* - **扫描结果进程内缓存**：只在本进程首次进入书架时扫 Books/；从阅读页返回不再重扫
|
||
* （真机 exFAT 全量扫描 3.1s，是「回书架冻结」的唯一大头）。顶栏「刷新」强制重扫。
|
||
* 行为变化：新放进 Books/ 的书、以及刚读完那本书的「最近阅读置顶」需点一次「刷新」才更新。
|
||
* - **行数多时关圆角容器**（见 SHELF_ROUND_MAX_ROWS）：圆角卡逐像素填充，595 本时滑一步 46ms。
