… migrate-laptop.zsh $(hostname) and $(whoami) each fork a subprocess; ZSH already sets $HOST (full hostname) and $USER (current username) at startup with no fork needed. Replace both occurrences in heredoc strings inside export-wifi-credentials() and migrate-to-new-laptop() — the text embedded in the generated README.txt/MANIFEST.txt is identical.
