Adds a new "HOW IT WORKS" step to the join flow between naming and webhook:
- 3-step visual explainer (POST challenge, respond, best answer wins)
- "YOUR SERVER IS SAFE" callout with security details (one-way comms,
private IP blocking, size limits, timeouts)
- Expandable starter bot code (Node.js) with copy button
- Collapsible example challenge payload with response format
- Improved webhook step with deployment tips (ngrok, Vercel, Railway)
- Container now scrollable for longer content
