# Registry bases (`base` and `radix`)

This folder holds **two parallel registries**:

- **`base/`** — Base UI–backed components and blocks  
- **`radix/`** — Radix-backed components and blocks  

## Keep them in sync

For any **shared** surface (same preview block, same card, same example intent), changes should be applied to **both** `base` and `radix` variants.

- Adjust only what must differ: imports (`.../base/ui/...` vs `.../radix/ui/...`) and primitive APIs.
- Avoid editing only one tree unless the work is intentionally scoped to a single base.

Project automation: see `.cursor/rules/registry-bases-parity.mdc` for the Cursor rule agents use when working under `apps/v4/registry/bases/`.
