/* Nodexa product - "Instrument" design system (light).
   The signed-in product: /signin, /app, /report, /app/settings, /admin.
   Replaces the dark terminal (app.css). Load together with instrument.css.
   Doctrine: paper + ink + ONE blue. Survey-instrument notation, hairline rules,
   mono numerals, serif only for dossier display headings. No gradients-as-decor,
   no glassmorphism, no orbs. Motion = precision (draw, stamp, count), never float. */
