/* ============================================================
   HSJ Motion — flipbook-first homepage stylesheet
   Layout model researched 2026-08-24 against kinfolk.com and
   thegentlewoman.co.uk: the cover is a physical object on a
   clean light page; issue title in centered serif above it;
   minimal chrome. Motion = paper depth, tilt, float — not
   gradients or decoration.

   Palette + type from design/DESIGN.md (never invent colors):
   bg #FBFAF7 · surface #FFF · elevated #F4F0E8 · ink #1A1A1A
   gold #C9A35A · palm #3B5C42 · sunset #D86A3A
   Playfair Display (serif) · Inter (sans)
