100455 safety composite

100455 scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 16%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
