/* ============================================================================
   Responsive — mobile is composed, not collapsed.

   FC1W rewrote this file around the new compositions and around design.md
   section 20: 20 to 24px of side padding, the image before the copy in an
   editorial row, journey cards in one column, the anchor navigation scrolling
   sideways rather than wrapping, a minimum of 16px on body text and 44px on
   anything you can tap.

   The rules that are gone are gone because the compositions they described
   are: the FC1V opening band, the France-by-river spread, the paired-portrait
   image rhythm and the old river and line page heads.
