Common errors

The user expects full YAML parsing or schema validation

Fix: Use YAML Validator if the main goal is to check correctness.

The YAML already contains structural indentation problems

Fix: Fix indentation issues first because minification is not a full YAML repair tool.

The user wants readable output instead of compact output

Fix: Use YAML Formatter when readability matters more than size.
