# Chrome Coins

> Objet pack asset: four polished chrome coins with rounded rims tumbling down in an endless drizzle, each popping in at the top and shrinking away at the bottom, raymarched in WebGL against studio softboxes so every flip catches the light. Leans toward the cursor and spins when dragged. The metal tint is a prop. Zero dependencies; any number share one WebGL context.

## Install

One-time setup (needs a subscription):

1. Add the registry to the project's `components.json`: `{"@assembli":{"url":"https://www.assembli.design/r/{name}.json","headers":{"Authorization":"Bearer ${ASSEMBLI_API_KEY}"}}}` (merge into `"registries"`).
2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/objet-coins/objet-coins.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/objet-coins
```

Registry item JSON: https://www.assembli.design/r/objet-coins.json (send `Authorization: Bearer <api key>`)
