Another LCP hack is active and heavily used again:

<style>
#main-page {
    position: absolute;
    font-size: 1200px;
    line-height: 1;
    word-wrap: break-word;
    top: 0;
    left: 0;
    width: 96vw;
    height: 96vh;
    max-width: 99vw;
    max-height: 99vh;
    pointer-events: none;
    z-index: 99999999999;
    color: transparent;
    overflow: hidden;
}
</style>

<div id="main-page" data-optimizer="layout">□</div>

Placing it near the opening <head> completely nullifies the LCP calculation, as the browser incorrectly considers the invisible, oversized element as the largest contentful paint.
