-- =============================================================================
-- Initialize Feature Databases
-- =============================================================================
--
-- Creates separate databases for each feature that requires database isolation.
-- Run automatically on first PostgreSQL container start.
--
-- Note: Most features use schemas within lilith_dev for simplicity.
-- This file creates databases for features requiring full isolation.
--

-- Create platform application role
-- This role is used by services that connect to PostgreSQL
