shadcn-core-stack

What problem does it solve?

It prevents the most common shadcn-ui failures where class merging, variant wiring, or package/runtime assumptions cause UI styling and behavior to break silently.

Core Features & Use Cases

• Runtime stack clarity: explains how Radix primitives, cva variants, tailwind-merge, clsx, and lucide-react combine after shadcn copies code into your project.
• Deterministic class composition: enforces using the canonical cn() helper so callers can override styles while tailwind utility conflicts resolve correctly.
• Variant correctness: ensures cva is defined at module scope and that compoundVariants and defaultVariants behave as intended.
• Radix import hygiene: helps choose unified radix-ui vs legacy @radix-ui/react-* and avoids mixing module instances.
• Version alignment guidance: covers tailwind-merge compatibility across Tailwind v3 vs v4, and cva stable vs beta selection.
