# Add document deletion functionality and fix UI theme issues
This PR adds the ability to delete documents and their associated memories across all content card types (Google Docs, Notes, Tweets, and Websites). Each card now includes:
- A delete button that appears on hover
- A confirmation dialog to prevent accidental deletions
- Proper event handling to avoid triggering card clicks when using delete controls
Additionally, this PR fixes various UI theme issues:
- Updates button styling in the ActionButtons component
- Improves theme consistency by replacing hardcoded colors with theme variables
- Fixes text color issues in login page components
- Ensures proper color contrast in various UI elements
The masonry layout was also improved to properly re-render when documents are removed.
