/*
   Strategy to avoid transform-on-fixed mobile glitches:
   The outer .bottom-nav-block is a fixed-position container that spans the
   full viewport width (left:0/right:0) but uses pointer-events:none so clicks
   pass through.  The visible pill is the inner .bottom-nav-inner which is
   centered via margin:0 auto and has pointer-events:auto so items are
   clickable.  No transform is used on the fixed element, which prevents the
   "hides on scroll" bug on iOS Safari & Chrome Android.
