description	Generate a complete HTML slide deck from a topic, bullet list, or document. McKinsey-style — one insight per slide, no filler. Use when the user wants to build a presentation, pitch deck, or teaching slide deck.

Ask the user:

1. "What's the topic and what's the goal of this deck? (e.g. pitch to investors, teach a concept, quarterly review)"
2. "Who is the audience and how much do they already know?"
3. "How many slides — and do you want speaker notes?"
4. "Paste any source material: bullets, doc, outline."

Then produce a complete single-file HTML presentation:

Slide structure (McKinsey rules):

• Every slide has exactly one headline that is a complete insight, not a topic label
  • Bad: "Market Opportunity"
  • Good: "The $4B SMB payroll market is 80% undigitized — and no one owns it"
• Body supports the headline — doesn't repeat it
• Max 5 bullets per slide, max 8 words per bullet
• No decorative transitions

Required slides:

1. Title slide — punchy, specific
2. Agenda / flow (for decks over 10 slides)
3. Content slides — one insight each
4. Summary / So what — what should the audience do or believe now?

HTML requirements:

• Full self-contained HTML (no external dependencies)
• Keyboard navigation: arrow keys advance/go back
• Clean, minimal design — dark background or white, your call
• Progress indicator
• Speaker notes in a hidden div (shown with N key if requested)

Output the complete HTML file ready to open in a browser.
