Lead Magnet Template, Test Page

What to test, in order

Confirm Backend health returns {"ok":true,...}.
Confirm Public config reads back what you set in Script Properties.
Click the chat bubble (bottom-right) and walk a full conversation. Aim for the bot to qualify and close the lead.
Submit the fallback contact form below to test the non-chat path.
Open your Google Sheet. Chats tab has all turns. Leads tab has one row each from chat and form, tagged and prioritized.
Check inboxes for the lead's confirmation email and (if priority/tag warrants) the renter's immediate notification.

Health endpoint returns 404 or HTML: the Apps Script web app isn't deployed, or the URL is wrong. Re-check Step 8 of SETUP.md.
Config endpoint returns empty values: Script Properties aren't set, or the Settings tab "Use This Row" checkbox is off. Script Properties is the source of truth, Settings tab is the optional override.
Chatbot shows "Something went wrong": open devtools, Network tab. The POST response has an error code. Common: verification_failed (Turnstile keys mismatched between site and secret), or 500 from Apps Script (check the Executions log).
Bot keeps asking questions, never qualifies: the model isn't producing the <lead> sentinel. Check the Chats tab for the raw assistant turns. If the sentinel is there but malformed, tighten the niche prompt in getPromptBody. If it's missing entirely, the prompt's completion contract isn't strong enough.
Form submits but no row in Sheet: check Apps Script Executions for the latest doPost run. Likely an exception in saveLead or a permission issue with Gmail.
Turnstile widget never appears: site key is wrong, or you're on a domain not registered with the Turnstile site. For local dev, add localhost as an allowed hostname in the Turnstile dashboard, or deploy to a Cloudflare Pages preview URL.
