Feature request: add dark mode support

[MIhraiz]

Would be great to have a dark mode option. Many users prefer dark themes for accessibility and reduced eye strain.

Some suggestions:

• Auto-detect system preference
• Toggle in settings
• Respect prefers-color-scheme

Happy to help with a PR if there's interest.

Happy to provide more debug info if needed.
