feedBack-desktop/tests/juce-exclusive-type-name.test.js

// Pins the JUCE WASAPI device-type names the shared player bundle keys on.
//
// The renderer decides "output is exclusive-style" by string-matching
// getCurrentDevice().outputType against 'Windows Audio (Exclusive Mode)'
// (see feedBack/static/app.js, _isExclusiveOutputType). That name is a
// hardcoded, unlocalised string inside the vendored JUCE. If a JUCE upgrade
// renames it, the feedpak-under-exclusive routing silently stops engaging —
// this test turns that into a build-time failure instead.
