/* ===========================================================================
   Mordecai Ardon — canonical site stylesheet (ONE design source of truth).
   Consumed by BOTH builders:
     - scripts/build_site.py   links this file from every generated page
     - scripts/build_sample.py inlines it into the self-contained previews
   Edit the design HERE, nowhere else. (site/assets/site.css is a build copy.)

   The core museum-wall design (palette, gallery grid, hover glow, lightbox) is the
   approved Option B. Caption spec follows the estate's direction: title in italic,
   date beneath, dimensions retained in data but HIDDEN for now.
