Replace the maps:create/update/delete catch-all for map features: roads, zones, and nodes each take a per-collection author permission, structure placement takes maps:place (still co-gated with the logistics qualification), and GeoJSON import requires all three author permissions. The map view page keys edit UI per feature type; admin role seed grants the new values. Tests updated for the permission split.
- map-zones type gains territory and country border (informational political
boundaries that never gate placement, default fills amber 0.1 / violet 0.06)
- map-roads labelVisible is tri-state: unset means auto, where paved roads
always label and dirt/trail only label at 4 m/px or finer (roadLabelShown)
- migration clears the old implicit label default on non-paved roads
- new pure snapping lib: findSnap (vertices own their neighborhood, edges must
be twice as close), closestPointOnSegment, segmentMidpoints
- tests for label angles, tri-state rule, snapping, political zones
Add pure routing, placement, point, and style libs plus map-system tests. Shipments gain a map relationship and routePath snapshot; ground vehicles route over the road network via Dijkstra while air and sea travel straight-line. Vehicle types declare a ground/air/sea transportMode and transit math works in meters.
