I’ve opened a PR to resolve this issue: #1633
It fixes the problem where light_mode=False did not apply dark mode correctly.
I fixed the issue where light_mode=False didn’t enable dark mode.
Refactored BrowserConfig (renamed to performance_mode, added dark_mode), updated browser_manager.py
to apply color_scheme='dark', added a dark mode test, verified with pytest, and cleaned up temporary test files.
Looking forward to feedback and review.
