Tailwind CSS Custom Plugins

Tailwind exposes three authoring paths for custom styles : the JS plugin() API (works in v3 and v4 for back-compat), v4's CSS-native @utility directive, and v4's @custom-variant directive. Pick by constraint, not by taste.

Companion skills :

• tailwind-impl-config-v4 : @utility, @custom-variant, @plugin directives in depth
• tailwind-impl-config-v3 : tailwind.config.js surface
• tailwind-core-v3-vs-v4 : version-wide API differences
• tailwind-syntax-functional-utilities : v4 --value() / --modifier()
