### Output Files

| File | Description |
|------|-------------|
| `preview.html` | Browser-based paginated preview (auto-generated) |
| `presentation.pptx` | PPTX file, right-click "Convert to Shape" in PPT 365 for editing |
| `svg/*.svg` | Per-page vector SVG, drag into PPT directly |
| `slides/*.html` | Per-page HTML source files |

### Requirements

#### Required

- **Node.js** >= 18 (Puppeteer + dom-to-svg)
- **Python** >= 3.8 (script execution)
- **python-pptx** (PPTX generation)

#### Auto-installed (on first run)

- `puppeteer` — Headless Chrome
- `dom-to-svg` — DOM to SVG conversion (preserves editable `<text>`)
- `esbuild` — Bundles dom-to-svg for browser use

#### Quick Install

```bash
# Python dependencies
pip install python-pptx lxml Pillow

# Node.js dependencies (auto-installed on first script run, or install manually)
npm install puppeteer dom-to-svg
```

    svg2pptx.py               # SVG → PPTX (OOXML native SVG embedding)
```

### Script Usage

```bash
# Merge preview
python3 scripts/html_packager.py <slides_dir> -o preview.html

# HTML to SVG
python3 scripts/html2svg.py <slides_dir> -o <svg_dir>

# SVG to PPTX
python3 scripts/svg2pptx.py <svg_dir> -o output.pptx --html-dir <slides_dir>
```

### Technical Architecture

```
HTML slides
  |
  v
[Puppeteer] opens HTML → [dom-to-svg] DOM direct to SVG
  |                         (preserves <text> elements, editable)
  |                         (base64 inline images)
  v
SVG files

  v
[python-pptx + lxml] OOXML svgBlip embedding
  |                    (PNG fallback for older Office)
  v
presentation.pptx
```
