Goo

Use when writing or modifying UI in an s&box project that uses the Goo framework. Triggers when Libraries/xaz.goo is present in the project, or when code or conversation mentions Blob, GooPanel, Goo.Kit, Goo.Shapes, Goo.Controls, Cell.Mount, or a ShaderEffect on a panel. Provides the Goo authoring rules, surface map, canonical patterns, and hard-won engine facts so output is idiomatic Goo on the first try.
