#  Agency PM — cPanel Quick Deploy Script
#  Builds the React frontend, uploads both backend and frontend via SCP,
#  then runs post-deploy commands on the server over SSH.
#
#  Prerequisites on your LOCAL machine:
#    - ssh / scp (standard on macOS/Linux, use Git Bash on Windows)
#    - node + npm (to build React)
#    - rsync (optional but faster than scp for large uploads)
#
#  Usage:
#    bash scripts/deploy-cpanel.sh              ← full deploy
#    bash scripts/deploy-cpanel.sh --frontend   ← frontend only
#    bash scripts/deploy-cpanel.sh --backend    ← backend only
# =============================================================================
