/* ==========================================================================
   Design notes (#/notes) — brief §15 handoff document
   A calm internal design-system doc on the site's own grid: a sticky contents
   rail (3 columns) beside a 9-column document whose inner grid lands on the
   page columns. Mono labels, fine rules instead of boxes, specimens on a dotted
   canvas, wide tables in labelled scroll regions. Colour only through tokens;
   panels on paper 2 re-point --fg-2 to --muted-2 (4.41:1 → 5.45:1).
   Scope: .nt (every selector starts with .nt)
