## 1. Implement geometry scaling and click sweeps

- [x] 1.1 Implement `get_window_scale` to parse actual window dimensions via `xdotool` (tests/run_e2e_tests.py)
- [x] 1.2 Implement coordinate scaling inside click simulation calls (tests/run_e2e_tests.py)
- [x] 1.3 Implement vertical Y-axis click sweep logic for GPU driver toggle buttons (tests/run_e2e_tests.py)

## 2. Verification

- [x] 2.1 Verify E2E tests pass successfully on the host display (tests/run_e2e_tests.py)
