/**
 * ShopLookbook — "Shop the look": a large editorial image with numbered hotspots. Each hotspot
 * opens a small product card (name, price, link and add to bag) and highlights it in the side list.
 *
 * @param {string} eyebrow - Small label. Default 'Lookbook'.
 * @param {string} title - Heading (use *asterisks* for italics). Default 'Shop the *look*'.
 * @param {string} text - Intro copy.
 * @param {{icon?: string, hue?: number, image?: string, alt?: string}} media - Scene visual.
 * @param {Array<{x: number, y: number, product: Product, href?: string}>} spots - Hotspots; x/y in % of the image.
 * @param {string} currency - ISO currency. Default 'EUR'.
 * @param {string} locale - Number format locale. Default 'en-GB'.
 * @param {string} cartKey - Cart storage key. Default 'ack-cart'.
 * @param {string} variant - Layout (image-left|image-right). Default 'image-left'.
 * @param {string} id - Base id. Default 'lookbook'.
 * @param {string} className - Extra class.
 *
 * Accessibility: hotspots are buttons with full labels and aria-expanded; the same products are
 * listed as plain links next to the image, so the look is usable without the hotspots.
