/* =========================================================
   İSTANBUL PİLİÇ — SHOWCASE
   Six products on one pinned, scrubbed stage.
   Spec: Figma "Showcase — Motion Spec"
   · stage bg butter/50 · diamond hairline frame
   · garnish particles (sparkle / daisy / burst / pebble / ring)
   · split-flap terminal (title top-left, detail card bottom-left)
   · detail card = "The Tag", 3 colorways (A sage / B forest / C coral)
   Motion lives in js/showcase.js — everything here is
   transform/filter/opacity-friendly (GPU-composited, no layout).
   ========================================================= */
