/* ==========================================================================
   region-cards.css — the three blocks below the photo carousel of the region
   detail page

     1. .na-flow          shared WATERFALL for both photo blocks.  CSS
                          columns, so every card keeps its own height and the
                          columns stagger — the waterfall look — while the
                          grid itself still reaches both edges.
     2. .na-cul-card      "Regional cuisine" — one waterfall card per dish
     3. .na-fes-card      "Festivals & events" — four festival cards plus two
                          season cards (same footprint, no photo)
     4. .na-fun-grid      "Fun & curious" — text-only trivia cards

   Every card is TEXT FIRST with a small photo thumbnail tucked beside it, so
   the whole description stays readable on screen: nothing hides behind a
   hover, nothing is clamped. Palette matches region-showcase.css.
