Metrics Lighthouse, mobile Chrome UX Report

Core Web Vitals: passing 2 of 3 assessed from real Chrome users.

Field figures are the p75 across real Chrome users over a 28-day trailing window (2026-07-26 → 2026-08-22), origin-level. From the backfilled CrUX history rather than this measurement, which predates the API key.
