I moved the front-end from setup mode into a real product experience by building the first complete dashboard screen for NihonGo!. The dashboard now loads live summary data from the API, greets the user, shows their current study progress, and highlights what they should continue next. I also added proper loading and error states so the page feels stable instead of empty.

To support that, I created a small set of reusable UI pieces like cards, stat blocks, and a progress bar, which made the interface much easier to structure and keep consistent. With that in place, the front-end now feels like the beginning of a full learning platform instead of just a shell around the authentication flow.
