60%95%+ passing Cell: pass rate, small number = p75 · faded rows: under 100 sites

One row per provider, one column per vital - the cell is the share of sites passing, the small number the p75. No toggling needed to see where the category actually differs.

Mapbox leads on LCP: 88% of its sites pass. Google Maps trails at 80%. computed
