Detailed Description

App lifecycle callbacks (shared by all instances of one app).

init runs once at registration; on_enter / on_leave bracket focus; tick + render run each frame while foreground; on_input routes events (returning whether the app consumed them); deinit tears down. Any callback except on_input may be NULL (a no-op). render is the only on-target one.
