/**
 * @fileoverview Field-notes design system for lunalabs.studio.
 * Rubber-stamp print aesthetic: warm paper ground, brick spot ink,
 * typewriter marginalia (Courier Prime) with Instrument Serif display.
 * Light ("paper") and dark ("night") themes switch via [data-theme] tokens;
 * the hero artwork swaps between day/night prints whose backgrounds are
 * normalized to the exact page colors, so they sit seamlessly on the page.
