The storefront is a grid of products (columns and products-per-page are
owner-configurable in Design), with search and category filter chips the
owner can each hide independently, plus a sort dropdown (default, price
low→high, price high→low, name A→Z/Z→A).
Clicking a product opens its own page: image gallery (the main photo is
shown whole, never cropped; tapping it opens a full-screen viewer with
tap-to-zoom, swipe/arrows between photos and pinch-zoom), badge, price (shows
"From " on a multi-variant product until a variant is picked),
optional crossed-out previous price, an "Included VAT" line if the owner
turned that on, description, and a variant picker if it has variants.
Out-of-stock products are hidden from the grid entirely by default
(the owner's "when out of stock" choice) — or, if the owner chose to keep
them visible, shown with a disabled "Out of stock" button and an optional
notice badge.
Cart
There's a real cart (saved in the customer's browser, survives a reload)
— browsing never skips straight to checkout. A cart icon in the header
opens it as a modal; once it has items, a sticky bottom bar and a floating
cart button (after scrolling) also appear as shortcuts.
Adding, changing quantity, or removing items all happen from the cart
without leaving the page. Quantity is capped at whatever stock is left for
that exact product/variant. A product with variants can't be added until
a variant is chosen — the button prompts for one instead of adding blind.
No per-order quantity limit — there's no "max N per customer/order"
setting. The only cap is stock: with "Limited quantity" set to 1, one
customer can buy it and then it's sold out for everyone (right for
one-of-a-kind items). With stock 10, one customer can take all 10. To
limit how many one person buys, say so in the product description and
adjust the order with the customer on WhatsApp.
