Uses constraints productively — maps hard limits, soft preferences, and how the tightest constraints define the solution space. Triggers: 'what are the design constraints', 'map the constraints', 'what are we working within', 'what's fixed', 'constraint-driven design', 'what does the solution space look like', 'working within limits'.
