* Hosts the React webview UI and bridges the reused Prism spectrum DSP to it.
|
|
*
|
|
* Drains stereo audio buffered by the processor, feeds the selected scope engine,
|
|
* and emits frame payloads to the webview. macOS uses display vblank; Windows uses
|
|
* a steady message-thread timer because some DAW/WebView2 embeddings deliver
|
|
* vblank callbacks too slowly for data-driven scopes.
