/* ==========================================================================
   SHOWCASE — tabbed glass-mockup section
   Replaces the legacy `.ui-showcase` on index.html. The legacy `.browser-window`
   chrome is kept in apple.css for other pages (product.html etc.) — this file
   doesn't override it. Single dark image per tab; the mockup floats above the
   bright marketing canvas with a 3D tilt + accent glow.
   Layer stack mirrors the recipe in §2 of the showcase prompt.
