/* tesseracollections.com: the public site (20 Oct 2026).
   The app's house style (tessera.css): ink and bone, verdigris for action, ochre for value, terracotta for "needs you".
   Type: IBM Plex Serif for headings (a museum label), IBM Plex Sans for reading, IBM Plex Mono for catalogue data
   (object numbers, dates, values). Cinzel only in the wordmark.
   Layout: a narrow reading column with wide "specimen" panels: record cards that show the product's own output. */
