/**

* Hosts the React webview UI and bridges the reused Prism spectrum DSP to it.
|
|
*
|
|
* Driven by a VBlankAttachment (message thread, synced to the display's refresh
|
|
* rate — so it adapts to 60/120/144 Hz panels). Each vblank it drains audio
|
|
* buffered by the processor, runs Visualizer::Spectrum (native/src/spectrum.cpp),
|
|
* and emits magnitudes to the webview as a "spectrumFrame" event. The webview
|
|
* (src/plugin-ui) renders them with the existing SpectrumAnalyzer canvas code.
