The app now has a real backend. A WordPress plugin exposes a REST-style API under /annemollerup_app/api/. The frontend connects to it and gets real data back.
Session management, user identity, and app state are all handled server-side. The frontend is a Vue-based single-page app that WordPress serves — decoupled but integrated.
This is the foundation everything else is built on. Solid architecture was a priority from day one, and it is paying off in how cleanly features are being added.
