/** * Observes devicePixelRatio changes (e.g. when a window is moved between monitors * with different scaling). Calls `fn` whenever the DPR changes. * * Uses matchMedia with a resolution query tied to the current DPR value. * When the DPR changes the query no longer matches, so we re-subscribe * with the updated value — this is why `once: true` is used. * * The callback is deferred to the next animation frame to avoid a race condition * where the `change` event fires before the browser has updated `devicePixelRatio`. * * @param fn - Callback receiving the current devicePixelRatio * @returns Unsubscribe function that stops observing DPR changes */ export declare function observeDPR(fn: (dpr: number) => void): () => void;
