This is the first page of the test PDF.
## Features
- Simple text
- **Bold text**
- *Italic text*
(Padding to ensure content...)
1. Item 1
2. Item 2
3. Item 3
# Page 2: Code Section
This should be on a new page if the previous content fills the page,
but since we don't have explicit page breaks, we'll rely on the structure.
Actually, let's just assume this is a single document we will modify.
