/* ---------------------------------------------------------------------------
   Three Hearts Support — front page for my.threeheartssupport.co.uk

   Built to the Brand Toolkit v1.0 (August 2026):
     - Cream leads. Navy and sage are accents, not default backgrounds.
     - Alternate the bands so neither navy nor cream dominates.
     - Playfair Display 700 for headings, 500 italic for the pull quote.
       Never for body copy.
     - Nunito 400 body, 700 labels, 800 for the wordmark.
     - Small sage text on cream FAILS contrast — sage dark #5F6B39 for labels.

   Grounding §8 is stricter than the toolkit on body size (18px vs 16-17px)
   because the readers are 50-70 and the people supported are 75+. The
   stricter number wins. Everything sizes in rem so 200% text scaling works.

   No external origin anywhere: fonts are vendored (D-006). Single deliberate
   light theme — the brand IS cream and navy — so every colour is painted
   explicitly rather than inherited from the host.
