📝 Dedent with Squiggly Heredocs​

The <<~ (squiggly) heredoc automatically removes leading indentation, letting you embed multi-line strings in indented code without unwanted spaces. It’s perfect for formatted text, SQL queries, or HTML snippets. Just ensure the terminator shares the code’s indentation level.
