/* ExpenseGauge — the public pages.
   ONE stylesheet decides how this site looks. No page carries its own.

   The palette is not new. It is the palette the application already draws
   with — the same deep navy, the same green — so that a visitor who signs in
   does not feel handed off to a different product. The application's own
   values are: ink #1a1a2e, green #2fae86, muted #7b8494, hairline #e9edf2,
   band #f5f8f7. Everything below is derived from those.

   Fonts are served from this server, never from a third party. The site's
   own privacy page says no other company watches you read it; a font fetched
   from elsewhere would make that sentence false. */
