SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The CSS theme-parity validator prevents regressions by ensuring that token declarations, color mappings, and theme file references stay aligned across the styling system and the theme switcher.

Core Features & Use Cases

  • Token parity checks across 9 theme files to guarantee every theme declares all required tokens.
  • Hex and rgba validations with a deterministic auto-fix pathway and human review for ambiguous cases.
  • HTML hygiene, unused styles suppression, switcher consistency, font parity, and swatch alignment to preserve reliable theme swaps.
  • Use cases include safeguarding theme swaps during site updates, introducing new themes, or preflight checks before commits.

Quick Start

Run the theme parity validator on site/css and related assets, then apply deterministic fixes with the --apply option.
