Create Tailwind Component

Scaffold a new CSS-only utility class in the Skeleton core package at packages/skeleton/src/utilities/. Tailwind v4 @utility syntax.

Where things live

• Utilities source: packages/skeleton/src/utilities/
• Import registry: packages/skeleton/src/index.css — every new file must be added here
• Reference files to model after:
  • Tailwind Utility: masks.css
  • Tailwind Component: buttons.css, badges.css, cards.css, chips.css
  • Form-related: form-inputs.css, form-selects.css, etc.
  • Typography: typography.css
