# DroppyKitThemeBridge

Enumeration

`enum DroppyKitThemeBridge`

## Type properties

### isHighlightColorProviderInstalled

`static var isHighlightColorProviderInstalled: Bool { get }`

Whether a host installed a highlight provider. `false` is the normal state outside Droppy (previews, the harness), where the tokens fall back to the system accent.

### resolution

`static var resolution: DroppyKitThemeResolution { get }`

Whether tokens are resolving in the explicit standalone or hosted mode.

## Type methods

### installHighlightColorProvider(_:)

`@discardableResult static func installHighlightColorProvider(_ provider: @escaping @Sendable () -> NSColor) -> Bool`

Installs the host's highlight-color provider. **Host processes only.**

The provider is called on every themed color read and must be cheap and thread-safe. The first call wins and later calls are ignored.

- Returns: `true` when this call installed the provider, `false` when one was already installed and nothing changed.
