   Per-chart platform filter
   -------------------------
   Lives inline in a chart card's header (only rating-trend and
   review-volume have one — see the comment on their markup) rather than
   the shared sidebar, so it's obvious at a glance which chart it applies
   to instead of looking like a global filter that silently does nothing
   to the other five cards.
