Parameterized toy: T(d) = k·d + c/(d+ε) on two qq̄ pairs. Coupling uses centered neighbor strain (strain/max − 0.5); strain integrates T/T_snap locked only. Not QCD.
Modes: Amplify / Oppose / Threshold-shift (see menu). Factor clamp [0.5, 1.5] on coupling. Chart blues = T_state norm (drives phases); strain follows raw T/locked snap.
