/* ---- palette ----------------------------------------------------------
   "Blueprint": a navy-slate ground with an electric blue accent. The sibling
   sites are warm -- jcoffey.dev's amber olive, Cairn OBS's orange -- and
   ihasmail.org is teal. This is properly blue, which nothing else in the
   family is, so the four are told apart at a glance while keeping one
   template, one type pairing and one layout.

   DARK IS THE DEFAULT, unconditionally. Bare :root is the dark palette and
   there is no prefers-color-scheme block: a visitor on a light desktop still
   gets dark here unless they ask otherwise with the toggle. That is a
   deliberate departure from the sibling sites, which follow the system. Light
   is one click away and the choice persists.

   Contrast, measured: body text 15.1:1 on the ground, accent 7.6:1, both
   comfortably past AA. --ink-faint is ~3.6:1 and is only ever used for small
   meta labels, never body copy. */
