2. Browser labs must include the WASM bootstrap and relative mlsysim wheel path.
3. Prediction widgets must be structured controls, not free-text prompts.
4. Interactive widgets must be returned through Marimo dataflow.
5. Runtime-installed WASM packages must be imported after micropip.install(...).
6. Labs should render tabbed parts plus a synthesis section.
7. Labs should save decisions to the Design Ledger where applicable.
