/* ==========================================================================
   Let's Begin Here — Climate & Rural Impacts  ·  Volume Two
   --------------------------------------------------------------------------
   A port of the INDEX stylesheet from Let's Begin Here: Rural Revitalization
   (lbhrr.hellodamien.com), measured from its live computed styles.

   That system is flat and editorial: square corners throughout, hairline and
   dashed rules instead of boxes, no shadows, transparent card fills, letter-
   spaced uppercase section headings, accent-coloured eyebrows, serif-italic
   display accents. The only rounded elements are the small header utilities
   and buttons, which are full pills in the reference too.

   Volume One is blue; this is yellow. Section colours are drawn from the same
   LBH secondary palette (teal, red-orange, blue, near-black).
