/* ihasmail.org — "stickers and stamps"

   The look is lifted from the cat itself. The mark is a flat drawing with a
   thick ink outline, in the cat's orange (#F9A34B) and the envelope's teal
   (#46CAC3), so the site is drawn the same way: ink outlines, hard offset
   shadows rather than soft ones, and the furniture of the post -- perforated
   stamp edges, airmail stripes, a wavy cancel line under the one word that
   matters. Silly name, serious mail: the drawing is playful, the type is a
   serious serif.

   Dark is the base definition on :root, and it is what everybody gets until
   they say otherwise -- the system preference is deliberately not consulted.
   Light exists only under [data-theme="light"], which the toggle sets and
   localStorage remembers. Every token is defined in the dark block, so none
   can go missing there.

   Navigation is a tab bar along the bottom, the way the app itself works on a
   phone, with a compose button beside it (it opens the demo). More opens the
   mailbox: everything on the site in folders, with a search line on top. */
