About this tool3 paragraphs

Every applicable score is shown (Base, Temporal and Environmental for v3.1; CVSS-B, BT, BE and BTE for v4.0), each with its band and the vector string it came from, computed by the official formulas.

The verdict is stated on the most refined score the vector supports: Environmental refines Temporal refines Base, so the last one you set is the one an analyst acts on. `cvss-cli` prints the same sentence.

The assessment of actual risk for any of these elements is entirely separate from what a score might say.
