* 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.

zero runtime deps, an offline test, and a README:
- PIP-Announce-Broadcast manual one-shot message to a screen/group
- PIP-Weather-Widget Open-Meteo current conditions (keyless)
- PIP-Air-Quality Open-Meteo US AQI widget (keyless)
- PIP-Crypto-Ticker CoinGecko price strip (keyless)
- PIP-News-Ticker scrolling RSS/Atom headlines
- PIP-Room-Status-Calendar ICS-driven Available/Busy room sign
- PIP-Event-Countdown client-side countdown, auto-clears at zero
- PIP-Welcome-Board rotating welcome/birthday cards from CSV
