V4 upgrade - Disable / remove SUBSCRIBE button / memberships?

Developer help

So after doing a dozen blog upgrades from Ghost v3 to Ghost v4/Casper v4, this worked best overall:

<style type='text/css'>

    /* Hide the Membership/Subscribe subsystem */
    a.gh-head-button,
    #ghost-portal-root,
    .footer-cta,
    .gh-head-actions,
    .site-footer a[href^="https://ghost.org"] { display: none; }
    .gh-head-inner { grid-template-columns: auto auto; }
    .gh-head-brand { max-width: 400px; }
    .site-footer-nav ul, .gh-head-menu { justify-content: flex-end; }

    /* make serif Article font match sans-serif index page font */
    /* Set font-family on body if you want to tweak it. */
    article.post p {
        font-family: inherit;
    }

</style>
