What is the Fix Shopify Storefront Performance Drift course about?

Every sprint introduces small frontend regressions , a lazy-loaded section that blocks LCP, a third-party script that inflates TTFB, a hydration bottleneck in React Server Components. Individually minor, they compound into failing Core Web Vitals. You fix them post-deployment, but the same issues reappear. You're stuck in a cycle of patching instead of preventing.
