/* =========================================================================
   naturephotos.website — skin "earth"

   Warm, slow and tactile. Terracotta and clay on a paper ground, soft diffuse
   shadows instead of rules, generous rounded corners and a deliberately
   unhurried transition curve. Where the grid skin is a system, this one is a
   surface: things sit on the page rather than being ruled into it.

   HAND-MAINTAINED. The forge never overwrites this file.
