/* ui/settings/settings.c — 设置页（ACT_SETTINGS）M3 骨架。
 *
 * M5 在此实现 APP 启动 PIN 等设置项；本批只落可编译桩，入口为书库 TopAppBar ⚙。
 * 返回：左缘返回（app.c SWIPE_LEFT → page_pop）。
 *
 * 接缝注意（M5）：meow_view 的 on_create 在 meow_view_create 内运行（activity 栈空）；
 * 本页是非根页，控件必须 lazy 到 on_enter 建，或照 hello demo_init 的模式
 * meow_ui_activity_push(ACT_SETTINGS) → 建控件 → meow_ui_activity_pop()
 * （examples/hello/ui/demo/demo.c:515-522）；否则 owner 绑到 ACT_LIBRARY，设置控件会从
 * 书库页被命中（§6.1 跨页泄漏）。
