" block in the SITE FOOTER. The original reads el.innerText and then writes el.innerText for every matching element. innerText is layout-dependent, so each read forces the browser to flush style + layout, and the write immediately invalidates it again -> read/write/read/ write layout thrashing (Lighthouse "Forced reflow"). textContent is not layout-dependent, so nothing is forced. Reads are also batched before any write. Whitespace is collapsed so the 100-character cut matches what innerText produced. --> ... ... ... jQuery (89 KB) + Slick (43 KB) are used ONLY by the case-study slider, which is far below the fold. Loading them on demand keeps 132 KB of parse/execute off the initial load (Total Blocking Time). The two Slick stylesheets are loaded here too, so they can be deleted from the site HEAD custom code where they currently block first render. -->
