shadcn-add

name	shadcn-add
description	Follow up cleanup and refactors that **must** be done whenever a new shadcn component is added via the add cli command. This skill should be checked whenever a new file is added to the shadcn ui component directory (`src/components/ui`).

Remove:

• The global React namespace import (import * as React from "react"); only import the concrete types and utilities needed.
• Any React. prefixes, both in types and in runtime code.
• The global export { } block; add the export keyword to each declaration instead.
• "use client" directives.
• Blank lines within the import statements.

Fix:

• Issues caused by having exactOptionalPropertyTypes enabled. This might require removing props from destructurings.
• Tailwind v4 modernization concerns (squashing data-['xxx'] attributes to data-xxx, converting arbitrary sizes to concrete values, e.g. size-[3rem] to size-12).

Organize:

• Sort imports via the vscode "Organize Imports" source action.
