/* imanotes front door (public-front-door, S-01).

   A three-page static site served by the server at /, /privacy and /terms —
   no build step, no script. The look is COPIED from the SPA rather than shared
   with it: the colour values below mirror the tokens in
   modules/client/css/style.css (:root and .dark), and the two faces are the
   same fontsource files the SPA self-hosts. Keep them in step by hand when the
   app's palette changes.

   Dark mode follows the OS (prefers-color-scheme) because there is no JS here
   to read the app's own ☀/☾ preference. */
