* Add PIP-Weather-Radar example (TV-style live radar overlay) A "cut to radar" PiP recipe: a Leaflet map (vendored locally for the CSP) with a CARTO dark basemap, an animated RainViewer radar loop, and live NWS warning polygons drawn and color-coded (tornado/severe-tstorm/ flash-flood/flood) with a pulsing "LIVE RADAR" HUD, count chips, and a legend. Auto-frames the view to the active warning polygon(s). Two modes: "always" (radar always up) and "on_warning" (default) which shows the radar only while a qualifying warning covers the configured point and clears it when the warnings expire — like a station breaking in during severe weather. 100% keyless / open data: RainViewer radar, CARTO/OSM basemap, NWS alerts. Zero Node deps; Leaflet is vendored client-side via vendor-leaflet.sh (gitignored). Offline test covers the warning gate, color map, RainViewer tile-URL builder, and overlay-URI round-trip.
