defaultEditorAssetUrls

The editor's default asset urls: none.

mocanvas serves nothing from a CDN. Its icons are inline SVG, it ships no translation bundles, and every built-in font face names a family that is already on the machine — so the map an app would override is empty rather than pointing somewhere. The *mechanism* is the point (assetUrls on the component, useAssetUrls() below it); an app that self-hosts fills this in, and one that does not never loads anything over the network.
