# Dark Mode Support

## Description

We need to add a dark mode option to our application to improve accessibility and user experience in low-light environments.

## Requirements

- Toggle switch in user settings
- System preference detection (respect user's OS preference)
- Persistent setting (remember user's choice)
- Properly themed components for all UI elements
- Appropriate contrast ratios for accessibility compliance

## Tasks

- [ ] Create dark color palette
- [ ] Add theme toggle component in settings
- [ ] Set up theme context/provider
- [ ] Implement system preference detection
- [ ] Refactor components to use theme variables
- [ ] Add theme persistence in user settings
- [ ] Test across all major browsers and devices
- [ ] Verify accessibility compliance

## Technical Approach

We should use CSS variables and a theme provider context to implement the theming system. This will allow us to switch themes without requiring a page reload.

## Resources

- [WCAG Contrast Guidelines](https://www.w3.org/WAI/WCAG21/Understanding/contrast-minimum.html)
- [Material Design Dark Theme](https://material.io/design/color/dark-theme.html)

## Implementation Notes

The main challenges will be ensuring all third-party components also respect the theme, and making sure we maintain proper contrast ratios in both themes.
