Install Foresite on Starlight

Starlight adds tags to every page's <head> from its head option. In astro.config.mjs:

import { defineConfig } from 'astro/config'
import starlight from '@astrojs/starlight'

export default defineConfig({
  integrations: [
    starlight({
      title: 'My Docs',
      head: [
        {
          tag: 'script',
          attrs: { src: 'https://t.foresite.dev/s/YOUR_SITE_ID.js', defer: true },
        },
      ],
    }),
  ],
})

Use the address from your own Foresite line (Settings → Install), then deploy. Visits to localhost aren't counted, so test on your published docs: the Installation Check in Settings → Install turns green with the first pageview.
