* TEMPORARY CSS Comparison Tool (TO BE REMOVED AFTER MIGRATION)
*
* Compare CSS custom properties coverage: sds-styling-hooks (source of truth) vs design-tokens
* Focus on ensuring design-tokens generates all the same CSS custom properties across shared & component scopes
*
* COMPARES: Scoped files vs scoped files (shared vs shared, component vs component)
* NOT: .json files - use temp-compare-json.js for JSON comparison
*
* Usage:
* yarn temp:compare:css # Summary only
* yarn temp:compare:css --verbose # Show detailed issue tables
* yarn temp:compare:css --report # Show full table of all properties
*
* NOTE: This is a temporary migration tool that should be deleted once the
* design token migration from legacy (Theo) to modern (Style Dictionary + W3C)
* is complete and verified.
