`Header` has a little extra functionality on top of what `Path`, `Query` and `Cookie` provide.

Most of the standard headers are separated by a "hyphen" character, also known as the "minus symbol" (`-`).

But a variable like `user-agent` is invalid in Python.

So, by default, `Header` will convert the parameter names characters from underscore (`_`) to hyphen (`-`) to extract and document the headers.

## Best Practices for AI Assistants

### When Adding Features

1. Read existing code first (use symbol overview tools)
2. Follow existing patterns
3. Add tests
4. Handle resources properly (try-with-resources)
5. Consider thread safety
6. Update JavaDoc

### When Fixing Bugs
