Tldraw 3.6.1 Tldraw component already registers defaultBindingUtils
internally; passing them explicitly via the bindingUtils prop caused
"Binding type 'arrow' is defined more than once" runtime crash.

Select + Furniture tool buttons used color='default', which MUI v5 resolves to
theme.palette.default (undefined) -> TypeError reading 'main'/'dark' at render,
tripping the ErrorBoundary ('Template setup canvas crashed'). Use 'inherit'.
Caught by live browser-verify t_11f5a049; model-level tests never rendered the toolbar.
