-// The same flyout the storefront uses, rather than the row of controls this
-// used to be (#169).
-//
-// That row was deliberate — it carried a comment arguing that hiding the
-// controls above a data table costs more than the space it saves, and that a
-// drawer overlays the very rows being filtered. Both are true, and both are
-// traded for the two screens asking the same questions through the same UI.
-// The chips are what makes the trade bearable: the active filter stays readable
-// beside the button without opening anything, which is what the always-visible

+// Published and Unpublished are distinctions only the admin can draw, and
+// favoriting is a customer's idea.
