   Pinned to the far right edge of the row itself (.t / .track-item

   block), the same way .ot-play-btn is pinned to the left edge.
   Track rows only define 3 grid columns (num / info / badge), so
   these buttons must be taken out of grid flow entirely — otherwise
   they land in an implicit 4th/5th grid cell, which pushes them onto
   their own row underneath everything else instead of sitting at the
   end of the track. renderStars() adds .ot-has-favbtns to the row so
   we can reserve room on the right without affecting rows that don't
   have these buttons. ── */
