How to Use

The parser handles multi-line strings, inline tables, and arrays-of-tables without manual tweaks.
Run the formatter
Whitespace and ordering are normalized while keeping comments and structure intact.
Copy updated TOML
Replace the original file or share snippets with teammates once formatting succeeds.
