React API

Core VEMU hook. Manages wasm init, board selection, firmware loading, the RAF render loop, UART I/O, and peripheral inspector state.

Default inspector view used for any peripheral that has no domain-specific view registered in `PERIPHERAL_VIEWS`. Renders the raw snapshot field map, pretty-printing any JSON-string fields. This is what makes "implement the inspector, see it in the UI" work before a custom view exists. Accepts the uniform PeripheralViewProps shape, so it can stand in for any registered view.

Generic peripheral inspector panel. A permanent section (like Display and Console): it always renders, lists whatever inspectable peripherals the live machine exposes, and shows a domain-specific view when registered, otherwise the generic fallback. Empty/error states keep it visible and diagnosable.

Vertical list of inspectable peripherals (the left pane of PeripheralPanel). Renders human-friendly labels via `peripheralLabel` and highlights the current selection.

Pixel-perfect display surface for the emulator's video output. Registers a draw callback that blits each RGBA frame into a 2D canvas, resizing the backing store whenever the frame dimensions change, and shows a "NO SIGNAL" overlay until the first frame arrives.

xterm.js console bound to the emulator's UART. Machine output is written to the terminal; keystrokes are passed through raw (picocom-style) as UART input. Auto-fits to its container and re-fits on resize.

Optional human-friendly labels for the selector. Unknown peripherals fall back to an upper-cased name.

Registry mapping a peripheral name (as reported by the machine) to a domain-specific inspector view. A peripheral without an entry here still appears in the list and is rendered with the generic fallback view. To add a richer view for a peripheral: write a component that accepts `PeripheralViewProps`, then add one line here.

Display label for a peripheral name: registered label or upper-cased name.

Branded title bar for the VEMU emulator window. Renders the `vemu.` wordmark as a link back to https://vemulator.com — every embedding carries attribution.

Uniform props every peripheral inspector view receives. Domain-specific views (KMU, UICR) and the generic fallback all implement this interface, so adding a new view is: write a component matching these props + register it in peripheralViews.tsx.

Everything useVemu returns: emulator status, board selection, program/run controls, video + UART wiring callbacks, and the peripheral inspector surface.

Optional override for testing / stub mode. Returned by the `loadModule` factory passed to useVemu to replace the default wasm loading.
