 * The annotation surface. Runs on pointer events only — never mouse events.

 * Mouse listeners are deliberately absent. Touch browsers replay a tap as
 * pointerdown/up followed by compatibility mousedown/up/click, so listening to
 * both would run the annotation logic twice for one tap and drop two pins.
 * Pointer events already cover mouse and stylus, so the desktop loses nothing.
