## Description

A1 Performance Snapshot gives developers, agencies, and site owners a fast local timing report for the active tab. Open the popup to capture Navigation Timing and Resource Timing from the current page. The report highlights DOM ready, load event, TTFB, known transfer size, requests by type, largest resources, and third-party domains. Copy a plain-text summary or export JSON and CSV for handoff notes. It reports local browser timing entries visible at capture time and does not replace Lighthouse, PageSpeed Insights, or lab and field Core Web Vitals tools.
