What this demonstrates

• Cells can return any HTTP status code and headers, not just JSON 200s
• 301 redirects: return { status: 301, headers: { location: "..." }, body: "" }
• C3 as a persistent counter store (click tracking with UPDATE ... SET clicks = clicks + 1)
• Input validation and 409 Conflict on duplicate codes
