- Weather Warnings overlay (layer key `wx`, saved in the view hash): NWS alert
polygons coloured by event (NWS hazard-map colours), outline dash by kind,
popup with event/headline/expiry/office and National Weather Service credit.
Polls GET /weather/alerts every 2 min while on and visible, refetches on pan.
A status chip always says what the layer shows; feed errors use the 511
FeedProblem wording; zone-only alerts are listed, never dropped.
- Radar: IEM nexrad-n0r -> n0q. Valid-time badge from IEM's n0q_0.json,
STALE past 15 min or when the time can't be read; dBZ legend; optional 1 h
loop (nexrad-n0q-900913-m05m..m55m), off by default. Still refreshed in
place, never remounted.
- liveWall: sampleRadarDbz reads the n0q tile with IEM's published 255-colour
ramp (verified against live tiles); pointInPolygon/alertsAt, wxStyle,
wantsWind helpers.
- Wall incident panel: "inside <warning>" chips, wind arrow + speed/gust +
station/obs time on fire/hazmat incidents; region Feeds gains an NWS row.
