Visual polish: dot markers, speed-as-brightness, finer geodata
- Replace directional carets with clean • dot markers
- Speed maps to color intensity (stopped=muted, fast=vivid) instead
of distracting pulse animation
- Station markers: · -> ○ in brighter color, show station codes
when zoomed in (viewport < 25 degrees)
- Selected station uses ◉ in cyan
- Re-simplified route data at 0.002° tolerance (was 0.008°) — lines
now stay continuous when zoomed in
- Re-simplified state boundaries at 0.005° tolerance (was 0.02°)
- Show heading text in station departure board instead of carets
