Landing page
Prose Landing page — "Sign in as an existing customer"
Why it works
Where Prose's win-back ads land: the same passwordless sign-in as the quiz's "Resume here". A returning customer types their email, gets a one-click link, and lands on their account with their formulas already on file. Anyone else gets "New to Prose? Start a consultation". A past customer's account page isn't shown here; a quiz lead's account page is shown separately.
