was staring at some terrible lcp numbers on a client site today. they're loading every single image in the gallery with priority instead of just the top one. if you don't use
fetchpriority="high"
on that first hero image, you're basically asking for a bad core web vitals score.
<img src="/hero.jpg" fetchpriority="high" alt="main banner">
it's a tiny change but it actually works when the main thread is busy. anyone else seeing huge delays on mobile despite having a good server response time?
