/* ui/full.c — 全屏页（ACT_FULL）view + 控制器。
 *
 * 无控件：进入时声明全屏+状态栏收合，绘制 accent 底 + 三行文本；点任意处/左缘左滑回 home。
 * 页面切换由 meow_view_page_push/pop 驱动 on_enter/on_leave（activity_push/pop 在 page_push/pop 内）。
 * 注：on_leave 里 activity_active() 仍为 ACT_FULL（activity_pop 在其后），故 OFF 日志的 activity
 *     id 与旧 set_fullscreen(0) 略异——纯诊断日志差异，功能无变化（见报告）。
