/**
 * sinopak/fg-hero block styles
 *
 * Prototype: 5-gallon-water-filling-machine-static/index.html —
 * .breadcrumb-band / .breadcrumb / .hero / .product-hero / .gallery /
 * .main-media / .thumbs / .thumb / .product-copy / .subtitle / .intro /
 * .product-summary / .summary-item / .hero-actions. All colours, gradients,
 * radii and shadows are literal copies from that stylesheet.
 *
 * The section is the first block of the product single and the site header is
 * position:fixed, so the root reserves exactly one header height
 * (--spk-x-header-h, declared in blocks/style-index.css :root; it becomes
 * 76px below 1180px).
 *
 * Shared primitives (.spk-x-fg-shell / .spk-x-fg-label / .spk-x-fg-cta) are
 * owned by the spk-base段 in style-index.css — only scoped tweaks here.
 *
 * Breakpoints: 1180px / 760px (prototype values).
