/* ---------------------------------------------------------------------------
   Logic-IT public site.

   Hand-written rather than generated, because the site is six pages and pulling
   in a build step (Node, Tailwind, a bundler) to produce this much CSS would put
   a whole toolchain on the deploy path for no gain. The design is unchanged from
   the previous site: stone greys, one orange accent, Fraunces over Inter, square
   corners, and hairline rules doing the work borders usually do.
