CookieYes Setup via GTM

My WordPress site is already running Google Tag Manager, yet CookieYes keeps blocking every Google-related script. I want to move the CookieYes snippet into the header manually—no plugins—then fine-tune GTM so consent is handled cleanly and all my tags fire as intended.

Here’s the current state:
• WordPress theme files are accessible, and I can paste code into header.php.
• All required GTM tags are already created.
• The scripts that must work after consent are: Analytics, Advertising, and general Functionality.

What I need from you:
1. Insert the CookieYes script directly in the header and configure it for full consent mode (no plugin involved).
2. Adjust my existing GTM tags and triggers so they respect CookieYes events—ensuring Google Analytics, Google Ads, and any functional scripts load only after the right consent level is granted.
3. Test in a staging or live environment, confirming:
– no console errors,
– cookies are set only after consent,
– pages pass Google’s Consent Mode checks.
4. Provide a short hand-off document outlining the changes (file edits, GTM trigger names, and how to add future tags).

If you know your way around WordPress theme files, GTM, and CookieYes, this should be a focused job that wraps up quickly and cleanly.
