First post for the site. Mostly a smoke test: headings, lists, code blocks, sidenotes, and citations all need to survive the MDX pipeline.

## What this checks

The site is built with:

- **Next.js** for routing and rendering.
- **Tailwind CSS** for the interface.
- **MDX** for posts that need components inline.

## The Detail

The goal is a writing setup that stays plain until a post needs diagrams, notes, or citations. <Citation id="jobs" index={1} />

<SideNote title="MDX note">
  This archived post is mostly here to exercise custom components.
</SideNote>

### Code Snippet Test

Here is the font setup pattern:

```typescript
const instrumentSans = Instrument_Sans({
  variable: "--font-instrument-sans",
  subsets: ["latin"],
  display: "swap",
});
```

## Next

Things worth writing down:

1. GPU kernels
2. Multi-agent systems
3. Research code that survives contact with experiments
