Priorities, not weights
Objectives are solved lexicographically: priority 1 alone, its result fixed as a constraint, then priority 2 within it. A lower priority can never cost you on a higher one. Scope any objective to a group — maximize demand met for the key accounts, then minimize inventory at the Iberian sites.
