- Geolocation: Uses standard HTML5 Browser Geolocation with high precision, backed by IP fallback geocoding (`geojs.io`).
- Graphics & Rendering: Features a SVG Bezier curve engine for smooth temperature and rain graphs.
- State Storage: App settings and history are stored 100% locally in your browser's `localStorage`.
