## Description

Daylight Cycle is a living theme — your browser follows the real sky.

<strong>By time of day:</strong> soft night blues before dawn, warm sunrise golds around 7am, bright clear daylight through the afternoon, golden hour, dusk purples after sunset, then back to deep night. It switches between light and dark mode automatically as the day turns.

<strong>By live weather (new in 1.2):</strong> grant the one-time location permission and your browser reacts to the sky outside your window:

• Cloudy — a soft gray wash over the daylight palette
• Fog — muted, misty green-gray
• Drizzle &amp; rain — cool rain-blue, deeper as it gets heavier
• Snow — icy pale blue-white
• Thunderstorms — dark, moody, electric

Weather refreshes every 30 minutes from Open-Meteo (a free public weather service). If you decline location or go offline, the theme quietly falls back to time-of-day only — it always works.

<strong>Privacy:</strong> your coordinates are stored only on your device and sent only to Open-Meteo to look up the current weather code. No analytics, no tracking, no accounts, nothing else collected — as declared in the manifest's data collection permissions.
