Rebuilt the store, lean
We moved off the heavy depot theme onto a clean Kadence child theme, stripped the page-builder bloat, and put a CDN layer in front. The result: mobile load time roughly halved and the homepage cut from 13.9 MB to about 1.6 MB, with layout shift held at zero. An interim CDN-only pass had already pulled the mobile paint down to under four seconds within days, with zero downtime.
