/*
 * VyaparMart experience layer — depth, motion and glass for the storefront.
 *
 * Deliberately dependency-free: every effect here is CSS transforms, gradients and keyframes, so the
 * page gains real 3D depth without shipping a WebGL library (which the CSP would block anyway, and
 * which would cost far more than it returns on a product grid).
 *
 * Everything is additive — remove the class and the element falls back to its plain Tailwind styling.
 *
 * ACCESSIBILITY: the whole file is disabled under prefers-reduced-motion at the bottom. Motion here
 * is decoration, never the only way to understand the page.
