Fix CLS for Guruhitech

My WordPress site guruhitech.com is currently failing the Cumulative Layout Shift check on Google PageSpeed Insights, especially on mobile. The largest unexpected movement happens in the main content area, and despite adding custom CSS, tweaking cache settings, and installing plugins such as Perfmatters, the score has not improved.

I need a specialist who can diagnose the precise elements causing the jump, stabilise them, and get the CLS metric comfortably within Google’s “good” threshold. You are free to use any performant approach—pre-sizing images, refining critical CSS, re-ordering script execution, lazy-loading, or other proven Core Web Vitals techniques—as long as it works reliably across modern mobile browsers.

Key deliverables:
• Audit the current theme, plugins, and critical rendering path to pinpoint layout-shift triggers.
• Implement code or configuration fixes that halt visible movement in the main content.
• Re-run PageSpeed Insights and share a before-and-after report proving the CLS passes for mobile and desktop.
• Provide a concise hand-over note explaining what you changed so future updates don’t reintroduce the issue.

I’m looking to move quickly—please outline a rough timeline and any similar sites you have optimised for CLS.
