Full side-by-side TEA comparison of 2-3 processes on one shared basis.

Recomputes each case's detailed TEA at identical operating hours, facility type, labor profile and financial assumptions, then returns per-case line items, per-kg cost breakdowns, deltas against the first case, and the warnings that keep a screening-grade comparison honest (different products block it; scale gaps, purity gaps and within-accuracy-band differences warn).
