/* Shadows of History -- The Archive
   Direction: a museum exhibition catalogue. Warm ivory paper, deep ink,
   Egyptian red ochre as the single accent (the colour of Ankhhaf's painted
   plaster), an editorial variable serif for display and reading, a quiet
   grotesk for labels. Cards are "double-bezel": a hairline tray holding a
   brighter sheet. Mobile-first at 390px; widened with min-width queries.
   The previous dark version is kept at .tmp/shadows-archive-content/style.dark.css */
