-!!! warning "Replace YOUR_KEY_HERE"
-    Edit the script and replace `YOUR_KEY_HERE` with your actual API key. Or if you've already saved it in `~/.bashrc`, replace the export line with `source ~/.bashrc`.
+!!! 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.
