/* Spora website styles.

   The tokens below mirror the Spora design system ("Instrument" direction):
   cool sage surfaces, ink text, IBM Plex Sans + Mono, a semantic color split
   (orange = act, green = success, gold = pending, rust = error), shape-coded
   status, flat color only, and the barcode strip as the one ornament.
   Design source: Claude Design project 9d253146 (local sync in ../spora-mac/_ds/).
   Rules marked "site:" are this website's extensions of the system (a marketing
   page reads at a larger scale than a 412dp phone screen). */
