IMPORTANT: After modifying this CSS file, you MUST update the version number in index.html!

Current version in index.html: styles.css?v=32
After making changes: Change to styles.css?v=33 (increment by 1)

This ensures users get your updated styles instead of cached old versions.
Without this, your changes may not be visible to users!

How to update:
1. Make your CSS changes in this file
2. Open index.html
3. Find: <link rel="stylesheet" href="styles.css?v=31">
4. Change to: <link rel="stylesheet" href="styles.css?v=32">
