Cost-controlled production is not a search for the cheapest version. A lower target price usually means trade-offs, and our job is to make those trade-offs visible: which substitutions are invisible to the end customer, which ones change hand feel or durability, and which ones touch function or packing. Some cost reductions may affect appearance, durability, structure or packing — we say which, in writing, before you decide. And if a target cost is unrealistic for the structure you want, we explain the gap clearly instead of quoting around it.
