Welcome to the **inline diff demonstration**! This text will be used to show different types of changes.

## Original Content

This paragraph contains some original text that we'll modify to demonstrate the diff functionality. You can see how different types of changes appear in each view.

### Features to Test
- Text modifications
- New additions
- Content deletions
- Line changes

## Conclusion

Try the buttons below to make different types of changes and see how they appear in both diff views!`,
