/* =====================================================================================================================
   Round 6 (client, 24 Sep evening). Loaded last (functions.php), so it overrides the page sheets.
   1. Rhythm: section padding averages 60px and never exceeds 120px (top or bottom).
   2. Surfaces: every section sits on the brand cream. A section that needs emphasis keeps its colour as a BLOCK (panel,
      ~60px inner padding) inside the cream — never a full-bleed brown / lime section. Brown is kept for the footer, the
      pre-footer form band (with a lime form card), small blocks, buttons and accents.
   3. The coloured lips / diagonal cuts between bands are retired (same cream on both sides).
   4. Phones: nothing swipes sideways — lists stack (base.css §18.2), carousels become grids (§7).
