WooCommerce Pinterest Pixel Fix for Termageddon / Usercentrics Cookie Consent Tool

woo-pin-tg-uc-fix.php

// Fix: Pinterest for WooCommerce pixel + UserCentrics consent
//
// The plugin outputs the Pinterest base code via echo in wp_footer — there's
// no filter to modify it. This snippet uses output buffering to intercept the
// full page HTML and replace the script type/attributes so UserCentrics can
// manage consent for the Pinterest pixel.
//
// What it does: changes <script type="text/javascript"> to
// <script type="text/plain" data-usercentrics="Pinterest"> inside the
// Pinterest Pixel Base Code block only. This targets both the standard and
// enhanced-match variants of the tag.
//
// Update-safe: the replacement key is the plugin's own HTML comment marker,
// which is a hardcoded constant in Tag.php. If the marker changes in a future
// plugin update, the fix silently stops applying (pixel reverts to default
// behavior) rather than breaking the page.
