Switching from Fathom Analytics to Plausible Analytics
Use the official compose at github.com/plausible/community-edition. Replace the Fathom snippet with Plausible's `<script defer data-domain="yoursite.com" src="https://plausible.example.com/js/script.js">`. There's no first-party Fathom importer (Fathom doesn't expose historical pageview data via API) — accept the calendar reset and start clean. Goals and custom events port one-for-one with the same hash-based event API.
