Zakie

A demo that generates the same brand guidelines twice: once from a stored, structured business profile, once from a blank prompt. That single comparison is the point of the app. Demo only — no accounts, no billing, no payments.

Environment

Variable	Used for
NEXT_PUBLIC_SUPABASE_URL	Supabase project URL
NEXT_PUBLIC_SUPABASE_ANON_KEY	Supabase anon key
SUPABASE_SERVICE_ROLE_KEY	Server-side database access
OPENAI_API_KEY	Generation, server-side only

Database

The business_profiles and assets tables already exist in Supabase; the app never creates, drops or migrates them. Row level security is enabled with no policies, so all access goes through server-side code using the service role key — the browser never talks to Supabase. A database trigger bumps version and updated_at, so the app does not manage versioning itself.
