lib/liveFilter.ts (pure): WallFilter {types, sevFloor, systems, talkgroups,
ageH, tags, q, preset}, applyFilter over loaded incidents + calls, parse /
serialise to the f.* hash keys #234 reserved. Presets: Fire (fire + EMS
assists heard on a fire channel; Radar on), Storm (weather/wires/tree/flood
tags; Radar on), Traffic (accident / MVA tags; Traffic Events on).
components/live/FilterBar.tsx: one wrapping row under the wall bar; less-used
controls fold behind a toggle below md; read-only summary in kiosk.
LiveView applies the filter once and feeds the filtered lists to MapView
(pins, paths, rail), RegionPanel, TranscriptTicker, TimeScrubber and the
auto-tour; KPIs count the filtered set and say "filtered". Presets turn
layers on through the saved-view layer state, not a MapView edit. Pipeline
health stays unfiltered. liveWall.ts keeps commas literal in f.* values.
