/* nshrt store — unified brand stylesheet.
   One palette + layout shared by the /shop storefront and the individual
   product landing pages (e.g. /ebooks/ship-while-you-sleep/). Tasteful, dark,
   minimal: a single indigo-violet accent with emerald reserved for price /
   confirmation. Keep both pages on this sheet so they read as one brand. */
