/* ==========================================================================
   ZUZU — Visual layer
   Loaded after style.css. Re-skins the greyscale wireframe into the first
   visual direction without touching its structure: warm paper surfaces,
   muted cloth-cover accents, Funnel Display for display type (#33), and real
   photography inside the existing .ph boxes.

   Direction pulled from Pinterest + Cosmos book/stationery references —
   Artifact Uprising-style floating hardcovers, cloth-bound spines on warm
   seamless backdrops, and typographic book design (big serif, lots of
   paper-colored negative space). See DECISIONS.md #24.

   All photography under assets/img/ref/ is TEMPORARY reference imagery
   (sources in assets/img/ref/SOURCES.txt) — it is not ZUZU's and must be
   replaced with our own product photography before anything goes public.
