   FEATURE BAND — full-bleed break in an article
   ============================================================

   A section element in normal flow, so it needs no viewport maths to span the
   page: it is a sibling of .csd-layout rather than something inside the text
   column, which is also why it can be full width at all — the column has the
   sticky rail beside it. --mist is the same #fafafa the other pale folds use,
   so the article's breaks and the site's alternating sections are one palette
   rather than two that happen to match today.
