/* =============================================================================
   Puzzle Baron site styles
   Design direction: "Puzzle Grid". Light ground, chunky geometric display type,
   and a per-offering accent colour that runs through each section.

   Accent is set with a --accent custom property on a section or card, so the
   same components recolour themselves depending on what they're showing:
