Added
- Weather radar on the live map. A new rain-cloud button in the radar's on-map controls overlays animated precipitation — the last ~2 hours of weather radar, looping smoothly so you can watch storms move. A small panel gives you a play/pause, a timeline of the frames (with the current frame's time shown in your configured timezone), and an opacity slider so the weather never buries the aircraft. It's off by default and remembered per browser. The data is free public weather radar (RainViewer) — no account or key needed; it just needs internet, like the map tiles.
Behind the scenes
- The overlay sits just above the basemap (below the aircraft, rings and trails). Frames are preloaded as separate tile layers and the animation hands off between them by opacity — so it cross-fades cleanly instead of blanking out and reloading on each step. The frame list refreshes every few minutes as frames age out (without disrupting the running loop); green→yellow→red follows RainViewer's light→heavy scale. RainViewer's radar has data up to zoom 7, so past that the overlay softens (upscales) rather than dropping out.
