Element style not allowed as child of element body

[vnevermore]

Theres a bad practise happening which leads to failure of html murkup validator test, and it can harm overall website(s) health.

<style> elements can't be child of the body element

    at style
    at NextTopLoader 

this happens on the nextjs 14.0.4
