# Master Demo Data Seeding Script
# Seeds all demo data for base template tenants
#
# This script executes all individual seed scripts in the correct order
# to populate the base demo template tenants with complete, realistic data
#
# Usage:
#   ./scripts/seed_all_demo_data.sh [--skip-existing]
#
# Options:
#   --skip-existing  Skip seeding if data already exists (idempotent)
#
# Environment Variables Required:
#   - DATABASE_URL or service-specific database URLs
#   - DEMO_MODE=production (recommended for consistent seeding)
#   - LOG_LEVEL=INFO (default)
#
