/* ===========================================================================
   Friday Long Post — site stylesheet
   ---------------------------------------------------------------------------
   Implements Design/README.md. Every colour, size and space below is a value
   from that handoff; where a number appears without a token it is because the
   handoff gives it literally (the type scale in particular is a fixed list of
   px values, not a ratio).

   Two rules the design is emphatic about, worth stating up front because they
   are easy to erode:
     1. NO SHADOWS anywhere, except the header's backdrop blur. Structure comes
        from hairline rules, not elevation.
     2. ONE accent hue. Do not add a second.

   Layer order: tokens -> reset -> primitives -> shared furniture -> views ->
   responsive. Responsive lives at the end in one block so the breakpoints can
   be read together; the handoff did not design them, so §Responsive documents
   the intent behind each.
