+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Implement an open-source mapping and routing layer for the canvas that provides advanced route planning capabilities beyond Google Maps. Built on OpenStreetMap, OSRM/Valhalla, and MapLibre GL JS.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [ ] #1 MapLibre GL JS integrated with tldraw canvas
+- [ ] #2 OSRM routing backend deployed to Netcup
+- [ ] #3 Waypoint placement and route calculation working
+- [ ] #4 Multi-route comparison UI implemented
+- [ ] #5 Y.js collaboration for shared route editing
+- [ ] #6 Layer management panel with basemap switching
+- [ ] #7 Offline tile caching via Service Worker
+- [ ] #8 Budget tracking per waypoint/route
+<!-- AC:END -->
