/* =========================================================================
   valleynaturephotos.site — skin "mist"

   Cold, deep and layered. The whole design is built on one idea: atmospheric
   perspective. Things that are further away are lighter and lower in contrast,
   and the page reproduces that in its surfaces rather than only in the
   photographs. The hero carries a slow drifting fog gradient built entirely in
   CSS - no images, no canvas, nothing to load.

   HAND-MAINTAINED. The forge never overwrites this file.
