/* Ascent Store — storefront styles
   Design direction: an engineering spec-sheet feel that suits a catalog of
   licenses/platforms with no product photography — ink + paper palette,
   a grotesk display face, and monospace treatment for prices/SKUs, the way
   a datasheet treats part numbers. */
