estimatedPitch is already corrected back to the original tone frequency
(the spectrogram computes from shifted audio, and updateSignalMetrics undoes
the shift), so adding toneShiftHz to it again placed the orange marker at the
shifted position - right on top of the green target line, making them
indistinguishable.
The orange marker now goes directly on estimatedPitch. When the original pitch
is outside the visible 400-1200 Hz band, an arrow at the nearest edge points
toward it instead.
