/**
 * Featured product card - sub-market template section 5 (spec 2026-10-01).
 *
 * One referenced product, emitted as a single full product card under the
 * payload key `productfeature`. All copy comes from the product record
 * (decision Olli 2026-10-01: dropdown only, no free text) - the front end
 * renders image, title and teaser from the same card shape the product
 * list delivers, so no second contract exists.
 *
 * Extends ProductListJsonRenderer purely to reuse its serializeProduct()
 * and image handling - same filters, same shape, one source of truth.
