/* Bargold: unrefined gold from Colombia.
   Palette: Andean night green (ink) and quartz paper, with raw gold. Follows the system light/dark setting.
   Type: Archivo (expanded widths for headings, like the stamp on a bar) and Alegreya for reading text;
   Noto Kufi Arabic and Noto Naskh Arabic for Arabic.
   Layout uses logical properties only (inline/block, start/end), so the Arabic pages mirror without overrides. */
