The demo (demo.pcbjam.com) cross-posts the waitlist to the marketing site's
serverless endpoint. It targeted the apex pcbjam.com, which 308-redirects to
www on Vercel; a CORS preflight can't follow redirects, so the OPTIONS failed
("Redirect is not allowed for a preflight request") and the POST never landed.
Point the waitlist target at the canonical www host. www.pcbjam.com already
returns 204 with access-control-allow-origin: https://demo.pcbjam.com, so the
preflight passes. Landing/version-badge link stays on the apex.
