Replace printf boot script with individual echo commands for mobile

Browse Source 
printf \n escapes also get mangled by Android clipboard (expanded to real
newlines). Individual echo >> commands are the only reliable approach for
copy-pasting multi-line scripts to a mobile terminal.

!!! tip "Why printf instead of heredoc?"
Heredoc (`<< 'EOF'`) blocks are unreliable when copy-pasting on mobile devices — trailing whitespace or clipboard quirks prevent the `EOF` from being recognized. The `printf` one-liner is more reliable for mobile copy-paste.
!!! tip "Why individual echo commands?"
Heredocs and `printf` with `\n` are unreliable when copy-pasting to a mobile terminal — the clipboard mangles escape sequences or adds trailing whitespace. Individual `echo >>` commands are the most reliable approach for mobile copy-paste.
