The CMS and analytics dashboard need the Node.js backend to read and write data. This deployment is the static build, so they're intentionally parked here.
To edit content and see analytics, run the project locally:
git clone … && npm install && npm start
then open http://localhost:4321/admin.
Or deploy the full stack on a Node-friendly host (Fly, Railway, Render,
or a small VPS) — the README.md has the steps.
