Test Units and Persistence
Task
Verify the unit preference affects every relevant display.
File / section
Browser
Change
Search a city, switch C/F, inspect current temperature, feels-like temperature, wind, and forecast, refresh, and confirm the selected unit remains.
Why this change matters
A unit change touches API requests, multiple components, and localStorage, so test it as one workflow.
Test it
All values use the selected system and the choice survives refresh.
Checkpoint
Units and persistence pass the integration test.
