# Stratum — AI Context Layer Landing

> AI context-layer template told as geological strata. An isometric core-sample hero with a scrubbable time ruler, chamfered problem cards, a stale snapshot beside a live record that rewrites itself, a cited answer with source popovers, a connector field, a compounding-value chart, a scope/monitor/audit security console and a use-case carousel.

## 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/stratum-landing/stratum-landing.tsx` and installs dependencies):

```bash
npx shadcn@latest add @assembli/stratum-landing
```

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