[FOR CODE] Output is meant to be written into the project source files. Everything changed with live-preview tools since the last clear: before → after per property, plus ready-to-paste code (vanilla Three.js and/or React Three Fiber) and where to find each target. Use it to persist a preview into source; call again with clear=true once the code is updated.
