The preferred method for precise layout positioning:
1. **HTML**: Create slides (720pt x 405pt). Text MUST be in `<p>`, `<h1>`-`<h6>`, or `<ul>`.
2. **Visuals**: You MUST rasterize gradients/icons as PNGs using Sharp FIRST. **Reference**: `references/html2pptx.md`.
3. **Execution**: Run `html2pptx.js` to generate the presentation.

<template_structure>
For deck editing or template mapping:
- **Audit**: Generate thumbnail grid (`scripts/thumbnail.py`) to analyze layout.
- **Duplication**: Use `scripts/rearrange.py` to duplicate and reorder slides.
- **Text Injection**: Use `scripts/replace.py` with the JSON inventory to populate content.
</template_structure>

- **Fonts**: You MUST use web-safe fonts ONLY (Arial, Helvetica, Georgia).
- **Colors**: You MUST NOT use the `#` prefix in PptxGenJS hex codes (causes corruption).
- **Layout**: You SHOULD prefer two-column or full-slide layouts. You MUST NOT stack charts below text.
- **Verification**: You MUST generate a final thumbnail grid with `--cols 4` to inspect for text cutoff or overlap issues.
