   Horizontal flow — a short sequence (2–7 steps) read left to right.
   The wrapper is a size container: when it is narrower than 44rem the
   flow turns vertical, so it also works inside half-width columns.
   Columns are equal width and there is no wrapping, so an arrow never
   dangles at the end of a row. Because the wrapper is a size container it
   takes no width from its content: place it in normal block flow or a
   stretched grid/flex item (add align-self: stretch inside an
   align-items: flex-start/center flex column).
