/**
* TEMPORARY Alias Comparison Tool (TO BE REMOVED AFTER MIGRATION)
*
* Compare aliases between @sds-styling-aliases and @design-tokens
*
* This script validates that all OKLCH values in design tokens
* produce the exact hex values expected by the styling aliases.
*
* 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.
*
* Usage:
* yarn temp:compare:aliases # Summary only
* yarn temp:compare:aliases --verbose # Show detailed list of issues
* yarn temp:compare:aliases --report # Show full table of all aliases
