+`ProductGallery.tsx` — main image + thumbnail strip, swappable on click,
+backed by an optional `Products.gallery` field (backend, `hasMany` upload,
+empty for most products — see the Payload README). Renders as a single
+plain image with no thumbnail row at all when `gallery` is empty, i.e. the
+same appearance every product already had before this existed — a product
+only gets the gallery UI once someone deliberately adds extra photos in
+the admin.
+
+There's no generic `/shop/[slug]` product detail page in this app — every
+product beyond the plain grid card gets a bespoke hero page (currently
+just `/todo-cards`), matching the custom-per-client site model.
+`ProductGallery` is wired into `TodoKartenHero.tsx` as a drop-in
+replacement for that page's static hero photo — but only once
+`product.gallery.length > 0`; otherwise the curated static lifestyle
+photo (`/hero-todo-karten.png`, deliberately not just the catalog image)
+stays exactly as it was. A future bespoke product page can reuse the same
+component the same way.
