/* --------------------------------------------------------------------------
   Section transitions

   Both modifiers used to paint a flat block (--bg-alt, and a light sage
   island for .section-contrast). Two opaque blocks meeting produces a hard
   horizontal seam, and a stack of those seams is exactly what makes a page
   look assembled from a template kit.

   The tonal shift now rides on a gradient that is fully transparent at 0%
   and 100%, so it grows out of the page and dissolves back into it. Nothing
   changes abruptly, so there is no line to see.
