/**
 * Single product: WooCommerce Flexslider gallery + related products carousel.
 * Brand accents align with Elementor landing (e.g. post-18: #1D1A46 headers).
 *
 * Layout strategy:
 *   - .single-product div.product: max-width cap + auto margins (box model, not full-width)
 *   - Inner flex: 35 % gallery | 65 % summary side by side
 *   - Elementor templates and WooCommerce default templates get the same proportions
 *     without either layout taking over the full screen width.
 *   - Mobile: column stack.
 *
 * Flexslider base: Hello Elementor and similar themes don't ship it; WC still
 * inits the slider.  Without these rules slides/nav look like broken lists.
