# Gift Stack

> Tinsel pack asset: a stack of three wrapped gifts, in polka dots, candy stripes and ribbon, with a bow on top. Every five seconds the lids pop in turn from the bottom up, the top one flipping its bow into the air, and each lands with a wobble. Raymarched in WebGL with a real ground shadow. Six palettes or your own colors.

## 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/tinsel-gifts/tinsel-gifts.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/tinsel-gifts
```
