It overcomes the lack of a public API, allowing users to analyze performance data from a specified date range into a highly formatted, actionable Excel spreadsheet. The output includes detailed per-note data, total engagement calculations, and summary statistics.

A portable CI gate designed to enforce Core Web Vitals (LCP, CLS, INP) budgets and category score floors on production frontend builds.
