Check my site's speed and tell me what to fix first

Measure how fast [site URL] really is and tell me what to fix first. Run the site through PageSpeed Insights (pagespeed.web.dev) for both mobile and desktop. Pull the Core Web Vitals — LCP, CLS, INP — plus the performance score, and screenshot both result pages. Then sanity-check the findings by loading the site yourself: note what visibly loads slowly, layout that shifts late, or heavy images. Repeat for [optional: one or two more key pages, e.g. pricing]. Translate the results into plain language: what is good, what fails the thresholds, and why it matters for users and SEO. Then give me the top five fixes ranked by expected impact versus effort, each naming the specific asset or behavior to change — not generic advice like 'optimize images' but which images, on which page.
