MeowOS-For-R3P2/patch_v2/ncm_app/app/ui/settings.c

/* ui/settings.c — 设置页（ACT_SETTINGS）。
 *
 * 行项：音质（Hi-res/较高/标准，默认 Hi-res）+ 缓存上限（1~100GB，默认 10GB）+ 退出登录。
 * 设置持久化到 MeowData/os.meow.ncm/data（meow_config_*；缓存上限键 ncm.cache_limit_gb 与核心库
 * ncm_cache_load_setting 对齐）。音质/上限经 BottomSheet 选择；退出登录经 confirm 弹窗。
 * 空态/绘制用 custom 绘制物 + 手动行命中（仅 3 行，无需列表滚动）。
