-- Local DB schema for development
-- This script is intended for running against a local Postgres instance (psql, Docker, or Supabase local).
-- Differences from supabaseSQLcreate.sql:
-- * Does NOT reference auth.users schema (no Supabase auth dependency)
-- * Does NOT enable RLS or policies (local dev convenience)
-- * Keeps indexes and FK constraints for referential integrity
-- Drop existing tables if they exist (safe teardown for re-creating DB)
