The classic installer asks the setup page's plan question before its yes or no, for a panel below its zone with DNS on Cloudflare.

• "Which Cloudflare plan is example.com on?" takes f for Free or p for Pro or Higher; CLOUDFLARE_PLAN=free or paid answers it ahead of time
• Free turns flat addresses on, prints the real addresses and that other sites on the zone will receive the panel's sign-in cookie, then lets n keep them under the panel
• Pro or Higher keeps every address under the panel without asking
• A domain not on Cloudflare keeps the plain yes or no
