A Shopify-style single-page checkout where the address field accepts a postcode, a free-form address, or a three-word address — switching between them is invisible to the shopper.

The address validator checkout flow scoped to the German market: search restricted to Germany, single address line, and postcode-then-city ordering.
A "Delivery instructions" textarea that auto-detects a three-word address typed inline, validates it, and stores it alongside the order — no UI change required from the merchant.
The same textarea integration in a right-to-left layout for Arabic-speaking markets — proving the component handles bidirectional text and mirrored layouts correctly.
