Classify all 65 LVĢMC stations reporting water temperature (56 inland WTEMD + 9 coastal SEDUT) into the six Ūdens zones by geography, and report the real min/max across each zone's currently-reporting stations instead of one hand-picked station's single value shown twice. Drops readings older than 12h so a stuck sensor can't skew a zone's range.
