Commit 930a9e70 by Lambert Theisen 🚀

Revert back to positive inflow (+sig_nn) for reason:

```1) Fully symmetric system ala:
|A   B^T| |x| = |f|
|B       0| |y|    |g|
2) Still have positive-definite system when stabilized in almost anti-sym formulation because:
=> d + f1 + f2 + h > 0 (quadratic term)```
