# One-shot DigitalOcean bring-up + smoke. Run it yourself so the cloud build and
# repo clone happen under your authority (the agent can't auto-clone private
# source onto cloud boxes; you can). It:
#   1. builds the golden image from the forge,
#   2. spins 1 worker, runs the test suite (timed) + a render proof,
#   3. tears the worker down (trap, even on failure).
#
# Launch and walk away:
#   nohup bash scripts/cloud-bringup.sh > ~/cloud-bringup.log 2>&1 &
#   # ...sleep... then on waking:  less ~/cloud-bringup.log  ;  open ~/Desktop/mc-do-proof.png
