Backend not configured yet

This page needs the Worker deployed and its URL set in index.html.

1. cd worker && npm install
2. npx wrangler secret put ANTHROPIC_API_KEY
3. npx wrangler secret put SUPABASE_ANON_KEY — the anon key, never the service role key
4. npx wrangler deploy
5. Put the deployed URL into WORKER_URL at the top of the script in index.html, then commit
