  Skriptorium: a scribe's room by oil lamp -- cedar, copper and papyrus.
   Signature: a cedar header closed by a double copper rule, warm lamplight
   on the page.
  An alternative look (point 6, 2026-10-04): the world layout with the
  engraving banners of the classic themes (app.css), its own pictures in
  images/themes/skriptorium (CREDITS.md) and its own colours. Text colours are
  checked for at least 4.5:1 on the card.
