All analog ports (IN-BAT, IN-WATER, IN-OILP, IN-RPM) now use R_high=100K,
R_low=27K — unified design confirmed in schematic. Updated .param values,
voltage divider netlist, verification comments, and design notes.
Vout @ 14.4V (alternator) = 3.06V — just at the ADC limit, correct.
Vout @ 15.5V = 3.30V — absolute maximum safe input voltage.
Filter fc = 747 Hz with 100K||27K and 10nF.
