/* Deliberately never viewport-fixed. Leaflet transforms its panes and the
   route atlas filters its tile layer, and a transformed or filtered ancestor
   makes a fixed child position against that ancestor instead of the viewport:
   the panel then lands in the middle of the map with its close button clipped.
   Absolute against the control is predictable everywhere.

   On a phone it tightens rather than grows, so a 300px-tall map keeps most of
   its geography visible behind a panel the reader can dismiss three ways. */
