OctoWeather Unit Tests

Same coords with different precision produce identical key

Nearby coords within 0.01° share the same key

Coords more than ~1km apart produce different keys

Key format is always "lat_lng" with 2dp

UV 0 → Low

UV 2 → Low (boundary)

UV 3 → Moderate

UV 7 → High (boundary)

UV 11 → Extreme

Code 0 → Clear

Code 95 → Thunderstorm

Unknown code → Unknown

Low pressure triggers pressure_low alert

Normal pressure produces no pressure alert

High humidity triggers humidity_high alert

UV ≥ 6 triggers uv_high alert

Temp drop ≥ 10°F over 3h triggers temp_drop

No alerts on benign conditions

Rainy condition → rainy sprite

Thunderstorm → rainy sprite

Clear daytime → sunny sprite

Clear nighttime → night sprite

Layer selector has z-index 2000 (from class z-[2000])

Map legend has z-index 1000 (from class z-[1000])

Layer selector z-index is strictly greater than map legend z-index

Gap between selector and legend z-index is at least 1000
