# This is the full workflow file with all fixes applied.
#
# It fixes:
# 1. Path errors (cd sge-backend)
# 2. Docker 'container removal' errors (by adding 'docker compose down')
# 3. Runs 'docker compose' from the correct directory (/home/ubuntu/Bgreen)
# 4. Combines backend and frontend into one efficient step
