Viewing a big track (10865-pt, 60km) and zooming/panning threw
'cc/tiles/tile_manager tile memory limits exceeded, some content may not
draw' dozens of times - Chromium's compositor tile-memory cap. The track
is drawn by Leaflet's default SVG renderer, multi-layered (casing/core +
per-1%-slope segments), so the giant SVG layer exceeds the raster budget
and the map tiles stop drawing until a force-stop resets the compositor.
Set preferCanvas:true on the heavy-vector view maps - showSessionDetail,
showRoadsMap (many road polylines, also reported laggy), showComparisonView,
showRouteDetail. Canvas draws into one viewport-bounded canvas instead of
thousands of SVG paths. Left the recording map on SVG (rotate:true;
leaflet-rotate barely supports Canvas) and the route editor (line clicks).
