Demo Animation

Generate a simple self-playing HTML product demo. Output: demo/index.html.

For most new demo requests, prefer demo-animation-v2. Use this skill when the user asks for the legacy desktop-oriented demo style or when a smaller, simpler demo is enough.

Workflow

1. Read the project README, app entry points, and relevant UI files.
2. Identify the product name, tagline, visual style, font stack, and 6-10 features to showcase.
3. Draft a brief demo step list. If the project is unclear, ask one concise question; otherwise proceed.
4. Generate a single self-contained demo/index.html file with no external dependencies except Google Fonts.
5. Include intro, dashboard mockup, animated cursor/highlights, sidebar captions, timeline controls, optional piano music, ending screen, and replay.
6. Validate that all referenced IDs exist, controls work, and the file opens directly in a browser.

Legacy Reference

If you need the original desktop architecture, read references/legacy-demo-engine.md. It contains the older detailed CSS, layout, animation, music, and quality checklist guidance.

Rules

• Keep the generated UI realistic for the actual product.
• Keep wait times reasonable: 800-1500ms for reading, 300-600ms for animations.
• Do not add network dependencies beyond Google Fonts.
• Do not use this legacy skill when the user explicitly requests mobile-first, touch, fullscreen, or highly responsive behavior; use demo-animation-v2 instead.

Output

Write to demo/index.html. Tell the user:

Demo created at `demo/index.html`. Open it in a browser to preview. Click "Watch Demo" to start the animation.
