@antebudimir/eslint-plugin-vanilla-extract/dist/css-rules/shared-utils/nested-selectors-processor.js

Comprehensive ESLint plugin for vanilla-extract with CSS property ordering, style validation, and best practices enforcement. Supports alphabetical, concentric and custom CSS ordering, auto-fixing, and zero-runtime safety.
