NOTABLE TODAY  (most extreme vs each pair's own history; surprise = how far the reading sits from the pair's own median, 0–100 [0 = at median, 100 = an own-history extreme; = 2×|percentile − 50|] — symmetric, so a deep-oversold reading scores as high as a deep-overbought one — a magnitude, not a trading signal)
