# Deploy backend: build release, stop running process gracefully (PID file & pgrep fallback), rotate logs, and start via nohup

# Usage:
|
|
# ENV_FILE=prod ./scripts/deploy_backend.sh
|
|
# ENV_FILE=staging ./scripts/deploy_backend.sh
|
|
# Notes:
|
|
# - ENV_FILE will be exported for the backend to decide which .env to load (e.g., .env.prod).
|
|
# - PID is stored in backend/udmin.pid.
