/**
 * Style 4 — isolated CSS, namespaced under .vynox-s4-card. The product
 * image fills the entire card as a background (unlike Styles 1/2/3's
 * square media box + separate white body below); a bottom gradient scrim
 * keeps the overlaid title/price/rating legible against any photo. Badge
 * sits top-left, wishlist top-right, both floating directly on the image.
 *
 * Reads the SAME --vynox-override-* variables the other styles do (see
 * Controls::register_style_controls()), except title/price default to
 * white here (this style's content always sits over an image+scrim, not
 * a plain card background) — still overridable from the Style tab like
 * every other style.
 *
 * The cart button is icon-only, anchored bottom-right; "View Cart" reveals
 * to its left on a successful add — same dynamic pattern as Styles 2/3
 * (WooCommerce's own wc-add-to-cart.js injects the
 * "<a class='added_to_cart wc-forward'>" link; nothing removes it here),
 * and driven by the same shared --vynox-cart-pill-bg custom property the
 * "View Cart Button" Style-tab section controls (see
 * Controls::register_cart_button_controls()).
