/* =========================================================================
   artivoorin.com — ato- design system

   Pure CSS Grid, Flexbox and custom properties. No framework of any kind and
   no JavaScript: the navigation and the FAQ are native <details> elements.

   The identity is a clinical lattice. A hairline grid is visible throughout —
   sections are built from bordered cells that share their rules, the way a
   spec sheet or a lab form does — on a bright, almost white ground with the
   packaging blues used sparingly and exactly.

   No object-fit:cover and no overflow:hidden above an image: every picture is
   sized by width and shown whole.
