/* ===========================================================================
   The listing shell shared by FAME's filtered lists (ebooks, classes, …).

   Everything above the results is here — the pill bar, the search field, the
   two-column layout, the filter rail, the toolbar and the pager — because the
   lists are the same page with different rows. Each list then ships only its
   own CARD stylesheet (fame-ebooks-list.css, fame-classes-list.css).

   The wrapper carries BOTH classes: class="fame-list-shell fame-ebooks-list".
   The variables live on .fame-list-shell so a second list inherits them without
   repeating the palette.

   Pills are radios and rail boxes are checkboxes, both marked
   [data-feb-filter]: fame-list-controller.js reads either and posts the chosen
   values with the search text and the offset, so a list needs no JS of its own.
