Map (MapView.tsx):
- Fan/hand-of-cards marker clustering: groups nearby markers by pixel
proximity (union-find), renders as rotated color cards showing all types
- Pulsing ring CSS animation on recording nodes (pulse-ring keyframe)
- Live incident overlay panel — right sidebar (desktop) / bottom drawer (mobile),
clickable to flyTo incident location
- Auto-fit button (⤢) fits all markers in view with fitBounds
- "Live · Xs ago" timestamp badge (refreshes every 10s)
- Weather Radar layer (NEXRAD via Iowa Env Mesonet, no API key)
- ADS-B + Meshtastic placeholder layers (off by default)
Map page (map/page.tsx):
- Fullscreen / kiosk toggle: fixed z-50 overlay covers nav, map fills viewport
- lastUpdated tracking passed to MapView for Live timestamp
Systems page (systems/page.tsx):
- Duplicate System button: opens form pre-filled with Copy of <name>
- RadioReference HTML import: file upload → DOMParser validates .rrlblue
structure, parses talkgroup categories, modal lets user select which
categories to import, auto-maps RR tags to local tags (law→police, etc.)
