# 06_run_services.sh - Service launcher
# =============================================================================
# Starts all selected services using Docker Compose via start_services.py.
#
# Pre-flight checks:
#   - Verifies .env, docker-compose.yml, and Caddyfile exist
#   - Ensures Docker daemon is running
#   - Makes start_services.py executable if needed
#
# The actual service orchestration is handled by start_services.py which:
#   - Starts services in correct dependency order
#   - Handles profile-based service selection
#   - Manages health checks and startup timeouts
#
# Usage: bash scripts/06_run_services.sh
