Score how hard a keyword will be to rank for from competitor strength signals.
Each dimension is scored out of 100 and combined using its normalised weight, so the result stays on a 0-100 scale. The weakest dimension is surfaced separately because a good average routinely hides one failing area. A single keyword difficulty number is what gets reported upward, but the weakest-dimension line is what tells you where the next hour of work should go.
