Product analytics: what the agents install

Install share by product

Install share counts the product each answer installed first. Mentioned counts answers that named it anywhere, picked or not. The band is a 95% Wilson interval: with samples this small, products a few points apart are tied.

### 1. Install

Run this command in your frontend directory:
```bash
npm install posthog-js
```

### 2. Initialize (e.g., in `src/index.js` or `src/App.js`)

```javascript
import React from 'react';

npm install next-plausible

    <html lang="en">
      <head>
        <PlausibleProvider domain="yourdomain.com" trackOutb
