 - Chromium is the only permitted browser runtime; never run Firefox or WebKit.
+- `blender-5.2.0` source and Blender Main are the behavior authority; web references are supplemental and must be recorded only when they affect build/runtime constraints.

 - Keep unrelated user changes. Never use `git reset --hard` or `git checkout --`.
