	 * chat" plugin, which near-universally docks at bottom-right with
	 * a ~20px margin and a ~50-60px button. Stacking this widget ABOVE
	 * that spot (rather than the more common bottom:20px) keeps both
	 * visible and tap-able instead of overlapping — the conventional
	 * pattern used by sites running more than one floating widget. If
	 * a site has no other floating widget, this still reads fine as a
	 * simple bottom-right position, just with a little extra breathing
	 * room above the page edge. */
