/* ---------------------------------------------------------------------------
   The couple portrait: a photograph, dissolved into the sky.

   The asset is an alpha cutout — the sunset background is already gone before
   the browser sees it. A mask can only soften an edge, it cannot remove a
   background, so pointing this at the untouched photograph would put a warm
   rectangle on a midnight page. See README.

   Three layers do the merging:
     1. `mask-image`   feathers the frame edges, hardest at the bottom and left
                       where the photo is cropped through the subjects.
     2. `filter`       cools and darkens the sunset grade into the page palette
                       while keeping the faces legible.
     3. `__wash`       a violet veil over the top, so the warm skin tones sit in
                       the same air as the starfield rather than on top of it.
