/* Archival Ivory + Seal, for the standalone article pages.
 *
 * These articles are static files under /public, so they can't import the React design library
 * or Tailwind's @theme. This is the one place the Ivory tokens are restated by hand — keep the
 * values in step with web-app/app/globals.css. One stylesheet for all three articles, so they
 * can't drift apart.
 *
 * Previously each article carried its own <style> block: a near-white ground (#fbf9f5), a
 * dark-brown gradient masthead and a dark-red accent (#7a1f1f) — warm in spirit but none of it
 * the museum's palette.
