Graphic Slide Deck

Generate a professionally designed HTML slide deck from a brief, content notes, or an existing file. Output is a single self-contained HTML file -- opens in any browser, no build tools.

Critical rules -- non-negotiable:

1. Every slide MUST fit within 100vh. No scrolling inside slides. Content overflows → split into two slides.
2. ALL font sizes and spacing MUST use clamp(). Never fixed px/rem on anything that scales.
3. Single self-contained HTML: all CSS/JS inline. Zero external dependencies except font CDN link.
4. Never dump HTML in chat. Save to file, show summary only.
5. No generic AI slop aesthetics -- check against the DO NOT USE list in references/style-presets.md.
