/* ============================================================================
   PLUMLINE — shared design system
   One stylesheet for every page. Change a token here, it changes everywhere.
   Layers, in order: (1) tokens, (2) base, (3) layout, (4) components, (5) utils.
   The plumb line is the through-line: a hairline that hangs down the left of
   the content, weighted by a small brass lozenge, the way a real plumb bob
   finds true vertical. It is the brand, so it lives in the base layer.
