# Weather-Adaptive Theming (Compose) The goal: exactly **one** place decides "what does hot/sunny/rainy/cloudy/winter/night look like," and every screen or component consumes that decision the same way — never a per-screen `if (condition == "Rain") Color.Blue else ...` scattered across composables. When a new screen, widget, or mood gets added later, it plugs into the existing system instead of forking it. ## Core mental model ``` Weather data (condition, temp, local hour) │ ▼ resolveMood(...) ── ONE function, pure, deterministic │ ▼ WeatherMood enum value │ ▼ toThemeColors() ── ONE mapping, mood → colors/icon │ ▼ CompositionLocal or shared ViewModel state ── exposed app-wide │ ▼ Every screen/component reads from the SAME theme source (hero card, app bar tint, widget background, notification accent — all of it) ``` ## 1. Mood resolution — factors in more than just the condition string ```kotlin enum class WeatherMood { HOT, SUNNY, RAINY, CLOUDY, WINTER, NIGHT } fun resolveMood(conditionMain: String, currentTemp: Double, localHour: Int): WeatherMood = when { // Night check first — a "clear" sky at 2am shouldn't theme as SUNNY localHour !in 6..18 && conditionMain in setOf("Clear", "Clouds") -> WeatherMood.NIGHT currentTemp >= 35 -> WeatherMood.HOT currentTemp <= 5 || conditionMain == "Snow" -> WeatherMood.WINTER conditionMain in setOf("Rain", "Drizzle", "Thund
