TOML format and conversion notes

TOML (Tom's Obvious, Minimal Language) is a config-file format used by Rust (Cargo.toml), Python (pyproject.toml), Hugo, and others. Key features: [sections] become JSON objects, [[arrays]] become arrays of objects, dotted keys like a.b = 1 create nested objects. TOML special floats (inf, nan) are converted to null since JSON has no equivalent. Datetimes are preserved as ISO 8601 strings. All processing runs in your browser.
