# Markdown to PDF Pagination Engine

This document tests the capability of the pure frontend pagination engine.

## Features
- GitHub-Flavored Markdown (GFM)
- **Live Preview** with accurate page boundaries
- Syntax highlighting via `highlight.js`
- Smart splitting of massive code blocks!

---

## 1. Margin Collapse Fix
In standard DOM, the bottom margin of this heading and the top margin of the paragraph collapse. The new engine measures elements *inside* the actual page container to track these collapsed boundaries perfectly, preventing prematurely short pages!

## 2. Manual Page Break
The `<div class="page-break"></div>` tag forced this content cleanly to the next page!

## 3. Oversized Code Block Splitting
Here is a very long code block to test smart splitting. It should gracefully split across pages without breaking syntax highlighting or overflowing.

```javascript

function finishTest() {
  console.log("This function should end up on a new page!");
  return true;
}
Note: Blockquotes are treated as atomic elements where possible to prevent ugly line breaks.
