Proof it's reusable: the second version (Koi Air, HND → SYD) was made by swapping content through the MCP using only the element names. Same timeline, new airline-logo and barcode images, retyped passenger, route, flight, gate, seat and class, and a new brand color in header-band. Because every element has a clear name, a full rebrand takes minutes, by hand or by an AI assistant.
