Workflow

Collect content from user: Ask for (or extract from conversation):

- Presentation title - Number of slides and topic of each - Any specific content, data, or key points

Plan slide layout: For each slide, pick the most appropriate layout type from the Slide Types above.

Generate the HTML: Write a single self-contained HTML file with:

- All slides in the <body> inside .deck - Each slide as a <div class="slide sN"> (with appropriate class for styling) - Correct slide numbering (01 / 07 format) - All CSS embedded in <style> tag - Navigation JS included

Save to file: Write the generated HTML to a .html file in the user's workspace.

Important Rules

One slide per viewport: Each .slide is exactly 1035×582px, overflow: hidden
No external dependencies: Do NOT use Google Fonts CDN or any external links. Use system font stack: 'Noto Sans SC', 'PingFang SC', 'Hiragino Sans GB', sans-serif
Consistent numbering: Use 01 / 07 format for slide numbers
First slide is active: The first .slide must have class active
Navigation always works: Include the standard nav JS exactly as shown above
Language: All user-facing text in the PPT should match the user's language (Chinese unless specified otherwise)
