/* ROTATION — "Liner Notes"
   The design system: printed matter, not a dashboard.
   Paper and ink, one spot color (Rotation red), and the typography of record
   sleeves and label copy:
     Archivo (variable width + weight)  — the voice: condensed for headlines, wide for labels
     Instrument Serif                   — the reader: facts, quotes, big italic numbers
     Geist Mono                         — the catalog: dates, units, matrix numbers
   Data is drawn in ink and the validated artist palette (js/viz/kit.js), on paper;
   immersive views turn the lights off (.night).
   Every page using this file sets <body class="liner">. Legacy components in
   style.css read the same tokens, so they follow along. */
