The NDL stylesheet was bundled into the ESM (twice) and shipped again as _css, so every widget display carried ~6 MB of the same CSS. Read it from the model's _css trait instead (anywidget syncs it; Streamlit seeds it) and drop the dead NVL layout worker chunks from the build output. widget.js 7.3 MB -> 3.2 MB, index.html 8.5 MB -> 4.4 MB, streamlit graph.js 7.3 MB -> 5.2 MB.
… Code)
Transitive UMD deps in the bundle (lodash, classnames, layout-base, cose-base, cose-bilkent, RBush) call the AMD define() when a loader is present. PyCharm/VS Code pages load requirejs, so evaluating the widget module raised 'Mismatched anonymous define() module', aborting it and tripping anywidget's 2s init timeout ('Failed to initialize model').
Neutralize the AMD branch at build time via define.amd = undefined.
