# Deploy to Dev Environment
# Automated deployment script for Show Prima dev server
#
# This script uses modular deployment libraries following atomic design:
#   - Atoms: Basic functions (_deploy-atoms.sh)
#   - Molecules: Combined operations (_deploy-molecules.sh)
#   - Organisms: Complete workflows (_deploy-organisms.sh)
#
# Usage:
#   ./scripts/deploy-dev.sh [OPTIONS]
#
# Options:
#   --seed-roles     Force re-seed roles even if they exist
#   --no-backup      Skip database backup (NOT RECOMMENDED)
#   --skip-checks    Skip pre-deployment validation checks
#   --branch=NAME    Deploy specific branch (default: dev)
#   --help           Show this help message
#
# Examples:
#   ./scripts/deploy-dev.sh                    # Standard deployment
#   ./scripts/deploy-dev.sh --seed-roles       # Force re-seed roles
#   ./scripts/deploy-dev.sh --branch=main      # Deploy main branch
