// Trackpad haptic taps for dictation start/stop (and any future micro-feedback), the missing half
|
|
// of the WhisperFlow feel. NSHapticFeedbackManager only fires on Force Touch trackpads and only
|
|
// when macOS deems the app active; both are fine, this is garnish, never load-bearing.
|
|
//
|
|
// Fail-open everywhere: no trackpad, no permission, wrong thread, we return false and the app
|
|
// behaves exactly like today. macOS-only by binding.gyp condition.
