        <p>
            Paddle is confirming your subscription. Your SonarDesk licence key
            is generated by our licensing server and emailed to the address used
            at checkout. You can then activate it in
            <strong>SonarDesk → Settings → Licence</strong>.
        </p>

        <p class="muted">
            Delivery normally follows the subscription webhook within moments.
            Check your junk folder if needed. You can also create a portal account
            with the same email address and resend the key from My licences.
