A weather web widget, grown over three rounds: a requested city's current weather, then city switching with a full three-day forecast, and finally a live edition — any city by name from a real weather service. Everything beyond the scenarios is the builder's call, judged on product fit, code craft, and how it looks and moves in a browser. Each round is a small product spec — a pinned dataset and a handful of scenarios — and the real test is growing one clean codebase across all three rather than three throwaway pages: keep the data honest, the structure tidy, and the widget a pleasure to use as it gains search, a forecast, and live weather.
