Current topic: "Hardening DemoMode and State Restoration"
Topic summary: I am now modifying `DemoMode.kt` to address concerns about brittle UI settlement. I will replace the fixed `Thread.sleep(2000)` with a polling loop that verifies the gesture navigation mode is active. Additionally, I will add logic to capture the original navigation state and restore it in `exit()`, ensuring a better experience for developers running tests on physical devices.

Strategic Intent: Harden DemoMode.kt by replacing brittle sleep calls with robust polling and improving state restoration.
