How to format and lint a YAML document

1. Paste your YAML

   Drop the YAML document into the "YAML" field. Any document the `yaml` library can parse — including anchors, multi-document streams (with `---`), and complex keys — is accepted.

2. What 'format' means here

   The tool parses YAML to a JS value with `YAML.parse`, then re-stringifies via `YAML.stringify` with lineWidth 100. Comments and original ordering of mapping keys are NOT preserved — this is a re-emit, not a pretty-printer.

3. Press Run

   Output is a single `formattedYaml` field with a normalised document — consistent indentation, quoting, and line wrapping at column 100.

4. Watch for parse errors

   Invalid YAML throws an error pointing at the line. Common culprits: tabs as indentation, unbalanced quotes, or a stray `:` inside an unquoted string. Fix and re-run.
