   The same design language as the application: warm brown and tan, Inter, and
   depth carried by a consistent elevation scale. A site that looks nothing like
   the product it sells makes the product look borrowed.

   No build step and no external requests. GitHub Pages serves these files as
   they are, and a page promising local processing while pulling fonts from
   Google would be a bad joke. */
