Merchants often chase page-speed plugins first. On Woo stores I reverse that:
- Capture LCP element (usually hero/PDP image or font block)
- Check TTFB separately from frontend weight
- Inventory third-party scripts on product templates
- Only then tune cache / CDN

If you’ve fought a stubborn LCP on variable products, what was the real culprit?
