/* The rail's nav is overflow-y:auto. A classic 6px scrollbar was being

   was centred in the remaining 54px instead of the 72px rail -- 2.8px
   off-centre, with a 6px gap on the left and 11.6px on the right. That
   asymmetry is the "off" look, and it only appeared when the list
   happened to overflow, so it came and went with viewport height.
   Reserving the gutter on both edges makes centring independent of
   whether the scrollbar is present. */

   scrollbar box there is no gutter to steal from one side, so the 6px
   padding centres the pills at every viewport height. scrollbar-gutter:
   stable both-edges also centres, but reserves ~21px of a 72px rail and
