# Hesabix one-click deployment script (server-side)
# - Clones from: https://source.hesabix.ir/morrning/hesabixArc.git
# - Prompts for API/UI domains and branch
# - Installs prerequisites, DB, backend (FastAPI), frontend (Flutter Web), Nginx
#
# Usage:
#   sudo bash deploy.sh
#   # or
#   API_DOMAIN=api.example.com UI_DOMAIN=app.example.com BRANCH=main sudo -E bash deploy.sh
#
# Notes:
# - Designed for Ubuntu 22.04+/Debian 12+
# - Idempotent-ish: safe to re-run; will update and restart services
