// renders (signed cookie, includes/membership.php), so we emit what the ad networks
// actually consume:
//  - Raptive/AdThrive: the `adthrive-disable-all` body class (their supported site-level
//    switch; the old `window.adthriveDisableAds` global is not used)
//  - Mediavine: a `#mediavine-settings` element with per-slot data-blocklist attributes
// Both are emitted with no provider detection. Each signal is inert on the other
// network's sites, so sniffing the installed network would only add a failure mode.
//
// Everything here is gated on the `adFree` benefit from a validated member session.
// Anonymous readers, non-members, members without that benefit, and invalid/expired
// cookies produce no output. Membership alone is not ad-free; the publisher has to
// enable the benefit.
