#!/usr/bin/env bash
# =============================================================================
# init.sh — One-time billing setup (run once, then just `docker compose up -d`)
#
# What this does (things compose can't handle):
#   1. Create .env from .env.example if missing
#   2. Run database migrations (billing tables in the platform DB)
#
# Prerequisites:
#   • Platform stack running (postgres healthy)
#   • Billing .env populated with platform-provided values
#     (PLATFORM_DB_PASSWORD, BILLING_SUPERUSER_PASSWORD, REDIS_PASSWORD)
#
# After init.sh completes: `docker compose up -d` is all you need.
#
# Usage:
#   ./init.sh                    # full first-time setup
#   ./init.sh --skip-migrations  # skip DB migrations
