Contract
- matchUtilities registers dynamic utilities that compile theme tokens and type-validated arbitrary values while rejecting mismatched data types
- negative utility classes place the leading minus sign before the configured prefix as .-tw- rather than .tw--
- configuring important with a CSS selector scopes utility rules under that selector without appending !important declarations
- addVariant registers pseudo-class and parent selector variants with proper prefix ordering
- resolveConfig merges theme defaults provided by plugin.withOptions into the configuration
