How css95/react-weather-app works
Weather Today is a React weather app for city search, current conditions and a seven-day forecast, with location-based weather and persistent favorites. The principal flow is search → routed city detail → geocoding and forecast requests → displayed conditions and forecast. The overview also supports location weather with a Stockholm fallback, and favorite cities can be revisited or removed. The graph includes documented overview capabilities whose component wiring was not sampled; those links are therefore limited. Responsive presentation is part of the UI, not a separate runtime subsystem.
