ASA Material Swapper

Paste an exported build template JSON (the clipboard export from ASA) or upload a .txt/.json file. Then swap structure tiers (e.g. Tek → Metal). Greenhouse pieces are detected but left untouched.

AUTO converts every supported material it can detect (except Greenhouse) into your chosen target. “Only convert X” leaves other tiers untouched.
Best supported: Tek ↔ Metal (vanilla + StructuresPlus). Others are best-effort.
