// - ESP32 v1 (original): Touch detected when value < threshold (capacitance increase causes value decrease)
// - ESP32-S2/S3 v2: Touch detected when value > threshold (capacitance increase causes value increase)
// This inversion is due to different hardware implementations between chip generations.
