A web address for a product
Runtime Market builds each product page's web address from the product's name, as a *slug* such as deluxe-pillow-blue-2-pack. Lower-case the name. Keep the letters a–z and the digits 0–9. Turn each space or dash into a single -, but never put two - in a row and never start the slug with one. Drop every other character, then remove a - left at the end.
