 * Newspaper-on-screen design system
 *
 * COLOUR PHILOSOPHY
 * All colours use CSS custom properties from layout.css :root /
 * html[data-theme] so dark ↔ light toggle works everywhere.
 * No hardcoded hex / rgb literals appear in this file.
 *
 * WCAG AAA contrast targets (7:1 minimum):
 *   --text-color on --bg          ≥ 16:1  (AAA ✓)
 *   --text-color-80 on --bg       ≥ 11:1  (AAA ✓)
 *   --text-color-55 on --bg       ≥  7:1  (AAA ✓)
 *   --brand-g1 on --bg (dark)    ≈  4.5:1 (AA — accent only, no body text)
 *
 * Three breakpoints:
 *   Desktop  ≥ 992px  : left-rail | center-hero | right-list
 *   Tablet   768–991px: full-width hero → 2×2 grid → newsletter
 *   Mobile   < 768px  : 2 heroes → tag sections (≤3/tag)
