/* Cancel Atlas — design system v2 "Accountability Ledger".
   Static, zero-dependency, zero external fonts (CSP + privacy + file:// safe), accessible.
   Aesthetic: investigative data-publication gravitas — system grotesque headlines + a Georgia
   serif evidence body + tabular-figure scores, warm archival ink, hairline rules, overline labels,
   pure-CSS atmosphere. Color encodes data (always paired with the number+letter), never moral
   judgment alone. DOM order == visual order (never reordered) so humans, screen readers, and
   agents read the same thing. */
