/* Invoice Partner — marketing site
   Theme lifted from the app's own "Ledger Indigo" tokens (web/src/theme/tokens.js):
   indigo #3B5BDB primary on a #F5F6FA canvas with white cards, Inter for UI
   type, JetBrains Mono for amounts, GSTINs and meta. Light by default and
   dark when the OS asks for it, same as the app. The phone mockups recreate
   the mobile app's invoice list and editor — not stock screenshots. */
