  • https://substr.cloud/author/bill/ — the likely hero/LCP image (feature-image.jpg) has loading="lazy" — Google explicitly warns against lazy-loading the LCP image, because it delays the fetch until layout completes. Remove loading="lazy" from the first significant image and add fetchpriority="high" instead.
