F12: routing an envelope to the frequency modulation amount

Retained analysis
ENV2's decaying contour maps to OSC1 FM amount. This makes the spectral interaction stronger/weaker through the note without requiring the amplitude envelope to have the same shape. A transient spectral gesture can be synthesized, not only sampled.
Documentation and visible configuration; not a new native audio test. Project observations are distinct from the source author's claims.
