/* app.c — hello 应用装配层：main + 组装 + 事件分发。

*
|

* 职责（SDK_VIEW_FRAMEWORK_DESIGN.md §B.2）：main 只做初始化/建页/跑事件循环/清理；把
|
||
* meow_ui_run 的平铺输入回调（key/tap/swipe/tick/touch）路由到当前活动页（home/full/demo）。
|

* 页面切换统一走 meow_view_page_push/pop（活动栈 + on_enter/on_leave 的唯一驱动，App 不再

|
||
*
|
||
* 契约（MEOW_APP_SDK.md §1/§3/§6）：应用只调 meow_ui API。
