/* ui/lock/lock.c — 锁屏页（ACT_LOCK）M3 桩 + M5 接缝。
 *
 * M5 在此实现「APP 启动 PIN」：lock_view_should_show() 读配置决定是否锁，
 * 锁屏页负责 PIN 输入/校验后 page_pop 回书库。本批桩恒返回 0（不锁），页面仅可编译占位。
 *
 * 接缝注意（M5）：
 *   ① meow_view 的 on_create 在 meow_view_create 内运行（此时 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_LOCK) → 建控件 → meow_ui_activity_pop()
 *      （examples/hello/ui/demo/demo.c:515-522）；否则 owner 绑到 ACT_LIBRARY，
 *      锁屏控件会从书库页被命中（§6.1 跨页泄漏）。
 *   ② 锁屏必须经自身 view 的 on_event 消费 SWIPE：meow_view_dispatch_event 先于 App 的
 *      on_swipe（sdk/meow_ui_view.h:83-88）；否则 app.c 对非 library 页的左缘滑动无条件
 *      page_pop，PIN 会被绕过。
