/* Pointer feedback (brush ring, lasso rubber band) lives on its own layer so
   following the cursor costs one clear plus a few strokes, instead of
   redrawing every raster cell, the fine grid and all parcel boundaries. It
   never takes pointer events -- #analysisCanvas below stays the event target.

   Its box is positioned and sized from JS in resizeAnalysisCanvas, mirroring
   #analysisCanvas exactly. Do not give it its own width/height here: being
   absolutely positioned it escapes the layout that sizes the main canvas, so
   a second declaration silently diverges, the shared backing store gets
   scaled into a different-sized box, and the drawn cursor drifts away from
   the real pointer. */
