/* Uniwai — Editorial Bold Design System (v8 · slate ink)
 * ------------------------------------------------------------------
 * Serif-led editorial direction. DM Serif Display for headlines +
 * wordmark; Inter for body; JetBrains Mono for metadata labels.
 *
 * Palette:
 *   • Warm cream paper (#FBFAF8, #F5EFE0, #EDE6D3)
 *   • Ink black (#1A1A1C)
 *   • Accent: slate ink (#1E293B) — deep neutral, NYT/Harper's vibes
 * The accent intentionally lives in the neutral spectrum: no saturated
 * "brand color". Character comes from typography and italic display.
