   Two of the three. The picker offers earth, white and dark; earth has no
   block here on purpose — it is the palette in base.css (and, on the history
   atlas, in history-profile.css), showing through when neither selector
   below matches. Adding a colour to one theme means adding it to both of
   these blocks and to the earth palette, or one theme quietly keeps the
   old value. */
