/* PayeeKit website. One stylesheet, no dependencies.

   The look is printed matter: a well-kept ledger, a clear bank statement. Flat paper color, hairline
   rules, a serif for headings, and real screens from the app where a picture helps. Deliberately
   absent, because readers now take them as signs of machine-made design: gradients, glass and glow,
   pill badges, rows of identical cards, checkmark bullets, decorative icons and stock people.
   AppStore/claude-design-prompt.md holds the same rules for the App Store screenshots. */
