Just the notebook content. +- **Read-only by default**: The embedded notebook should be viewable and runnable but not editable (no cell reordering, no adding/deleting cells). A URL param `?editable=true` could unlock editing if desired later. +- **Runnable**: Users can click "Run" on SPICE cells and see waveform output. This requires the FastAPI backend to be reachable. +- **Minimal layout**: Markdown cells rendered, SPICE cells with syntax highlighting, waveform output below each cell. Essentially the NotebookEditor component minus the editing controls. + +### 2. Theme support via URL param + postMessage + +The Mims library site has dark mode. We need the embed to match: + +- **Initial theme**: Accept `?theme=dark` or `?theme=light` URL parameter.
