Deep Time: didgeridoo opening, theremin emotional break, low vocal, quieter harmonium

Browse Source 
- Didgeridoo opens the track (vol 0.08, fades over 24 bars)
- Theremin enters bar 21 with slow bending melody — the emotional core
- Vocal synth "ohhh" at low octave (B1, F#1 range) from bar 16
- Harmonium pulled back 0.1 → 0.06
