Shop Header Editorial

---
/**
 * ShopHeaderEditorial — Editorial store header: thin announcement line, left menu, centred
 * wordmark, right utilities (search, theme toggle, bag count) and a full-width mega menu.
 *
 * @param {string} brand - Wordmark text. Default 'Forma'.
 * @param {string} brandHref - Wordmark link. Default '/'.
 * @param {string} announcement - Top line text (empty hides it).
 * @param {Array} links - `{ label, href, columns?: { title, links: {label, href}[] }[], feature?: { title, text, href, icon?, hue? } }`.
 * @param {string} searchHref - Search page URL (empty hides the icon). Default '#'.
 * @param {string} bagHref - Bag page URL. When empty, the bag button opens a CartDrawer instead.
 * @param {string} cartKey - Cart storage key for the live count. Default 'ack-cart'.
 * @param {boolean} themeToggle - Show a light/dark toggle (html[data-theme]). Default true.
 * @param {string} currentHref - Marks the active link.
 * @param {boolean} sticky - Stick to the top on scroll. Default true.
 * @param {string} variant - Style (paper|transparent|inverted). Default 'paper'.
 * @param {string} size - Height (sm|md|lg). Default 'md'.
 * @param {string} id - Base id. Default 'shop-header'.
 * @param {string} className - Extra class.
 *
 * Accessibility: mega menus are disclosure buttons (aria-expanded) that close on Escape/outside
 * click; the mobile menu is a disclosure too; the bag link label includes the live count.
