# Plenum — Indoor Air Quality Landing Page

> An indoor-air landing page between hairline rails: a painted sky through a rippling louvre behind a live CO₂ floor-plan dashboard, a method that autoplays through technical figures, a bento with alerts, an API panel and a year-of-air chart, a duct diagram of integrations, per-room pricing with a slider, before-and-after stories and a wind-tunnel CTA that flows around the cursor.

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

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

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

## Code

> Component source needs an Assembli subscription ($12/month or $96/year) and an API key sent as `Authorization: Bearer <key>`. To get one without copying anything, POST https://www.assembli.design/api/agent/login (or call the MCP tool connect_account), show the user the link it returns, and poll https://www.assembli.design/api/agent/token for the key. Or subscribe at https://www.assembli.design/pricing and create a key at https://www.assembli.design/account.
