   Reader bar — the same controls a visitor had on their reader track (the
   track chip and the Auto / Light / Dark pill), shown on articles only when a
   skin is active. js/reader-bar.js builds it.

   Laptop: a slim bar under the navigation.
   Phone: docked at the bottom, in thumb reach, like the tracks' docked bars.
   Built from theme tokens only, so it matches every skin in light and dark.
