/* ============================================================
   Kate's Quest — Elevation & Shadows
   ------------------------------------------------------------
   Cards cast soft, warm, slightly long shadows — like paper resting
   on a desk in afternoon light. No cool/blue shadows. There is also
   a set of "ink press" inner shadows that mimic letterpress and the
   debossed edge of a stamped seal.
