   Uses brand.css tokens, so it theme-flips automatically.

   Two presentations, switched by .is-collapsed on .jb-ws
   (added server-side by the partial once a choice exists):

     default        UNCHOSEN — prominent centred pill (as it was)
     .is-collapsed  CHOSEN   — discreet gear, bottom-left by the
                              cookie toggle; .is-open pops the pill
