-!!! 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.
