Single-file vanilla JS dashboard at ui/sultee-tracker.html:
- Connects to ws://100.64.0.2:9090 (configurable, saved in localStorage)
- Parses {"type":"gps","data":{...},"timestamp":...} JSON frames from iPhone
- Leaflet.js + OpenStreetMap tiles with dark CSS filter
- Live position marker (cyan pulsing dot SVG icon)
- Orange polyline trail (up to 2000 points)
- Auto-centers on first GPS fix; FOLLOW/FREE toggle; drag disables follow
- Sidebar: speed (km/h, color-coded), altitude, heading, compass rose canvas,
h-accuracy bar (green/amber/red), coordinate display, fix count
- Scrollable trail log with timestamp + coords + speed per fix
- Exponential backoff auto-reconnect (2s→30s cap)
- CLEAR button resets trail, marker, log, fix count
