/* Lente's website (ship-hackathon 5.1, design 6b): the app's own look on a bigger canvas. Plain CSS,
   no web fonts; one tiny script (theme.js) only for the light/dark switch.

   The color, type and elevation tokens mirror src/theme.ts (the tokens the web app loads), with the
   same names and values, copied here because the site has no build step: keep them in step. The
   navigation glass and the spring curves come from the iOS kit (docs/design/ios-kit/nav.css). Every
   text pair keeps the app's 7:1 contrast. Light is the default; dark is html[data-theme="dark"],
   set by the switch. */
