/* Layout: a marketplace feed on warm paper. Sticky top bar, a brief with the
   screen's meters, a 3 x 2 grid of listing cards (2 columns on phones); a
   listing opens as a sheet. Every object carries the art's plum ink outline
   and a flat offset shadow, as the TikZ pictures do.
   One deliberate look in both themes: the palette is Sam_Comm_final's. */
