Research direction
No files, tests, or entry points are named. Start by locating the existing browser timing standard metrics and the page view metric path, then determine which proposed Core Web Vitals are supported and how their completion should be verified. Done means the agreed paint metrics are tracked as standard metrics rather than requiring custom metrics or extra page view properties.
