Where it goes

A returning customer who enters the right code goes straight on (home, or booking); only a new customer sees Name and Add a vehicle. The Verify button in the drawing leads to Name so the first-sign-in path can be clicked; for a returning customer use the link above.
A service tile arrives as ?service=<key>. It is carried through every step (the States bar and the buttons keep it) and handed on as book.html?service=<key>. With no service the customer goes to Home. Try ?service=oil.
With a service, the number step says “You’re booking: Oil Change. Sign in to continue.” (the six names from the start page). This line is a proposal.

?

? Whether the name and email can be changed later. The spec does not say; not drawn in Account.
? What the email is used for (the app texts only). Waits on the client.
Skip for now is allowed (owner, 2026-11-09). The client still has to confirm it (open-questions).
? The consent sentences are drawn plainly; the legal wording waits on the 10DLC registration (build).
