The code

Bind `on:submit` with a handler that serializes the form and POSTs to FormLoom. Use a reactive `status` variable for the UI.

Tips

  • Make email optional to lower friction for quick feedback.
  • Pipe feedback to Slack via a webhook for real-time triage.

FAQ

No — keep email optional so people leave quick feedback without committing.
