One-time setup needed

This page uses a free Supabase project for accounts and storage, so it works on any website — including GHL. Before this will work, someone needs to:

1. Create a free project at supabase.com
2. Open the SQL editor and run supabase-setup-auth.sql
3. In Supabase, go to Authentication → URL Configuration and set the Site URL (and add a Redirect URL) to the exact page URL this file will live at — magic-link emails will silently fail to log people in if this doesn't match
4. In Project Settings → API, copy the Project URL and anon public key
5. Paste both into SUPABASE_URL and SUPABASE_ANON_KEY near the top of this file's <script> tag
6. Re-upload the file to GHL
