      summary: Create Checkout Session
      description: 'Start a paid-plan subscription, or change an existing subscriber''s plan.


        Free/guest users get a Stripe Checkout Session (locked to their account

        email so the webhook''s email-match upgrade applies) and a `checkout_url` to

        redirect to. Existing paid subscribers have their live subscription updated

        in place (prorated) instead of opening a second one — which would

        double-bill — and get `{checkout_url: null, updated: true}`.'
