Dynamic Weather Themes

Map Weather Conditions to Themes
Task
Use the existing weather helper to choose the app theme.
File / section
src/utils/weather.js and src/App.jsx
Change
Use the existing themeForWeather(id, night) mapping. In App.jsx, calculate const night = weather?.weather?.[0]?.icon?.endsWith("n"); and const theme = weather ? themeForWeather(weather.weather[0].id, night) : "clear";.
Why this change matters
Keeping the mapping in a utility makes the theme rules easy to reuse and review.
Test it
Search for conditions with different weather codes and inspect the root class.
Checkpoint
Weather data now determines a semantic theme name.
const night = weather?.weather?.[0]?.icon?.endsWith("n");
const theme = weather
? themeForWeather(weather.weather[0].id, night)
: "clear";
