Lyrics:
Verse 1
Under bright screens in a late-night lab,
Numbers glow where the quiet answers hide,
Same stimulus, same river in the vein,
But two different currents decide.

Pre-Chorus
Split the signal, watch it rearrange,
What looks "the same" won’t stay the same,
A single letter can tilt the scale,
And still we’re calling both by one name.

Chorus
Two keys in the same blood, turning different doors,
One sparks the fire, one softens the roar,
If we listen side by side, the pattern becomes clear,
Not one immune song—two harmonies here.

Verse 2
A TOX-shaped switch in one set of hands,
Pushes IFN-γ up through the night,
An EGFR-shadow near another line,
Lifts IL-10 like a calming light.

Bridge
Don’t average us into silence,
Don’t blur the edges of the proof,
Some maps only show their pathways
When you let them tell the truth.

Final Chorus
Two keys in the same blood, turning different doors,
Precision needs the split, not the pooled and smoothed-out score,
So read the heat in context, let the data steer,
Not one immune song—two harmonies here.
