one/types/link/prefetchIntent.d.ts

One is a new React Framework that makes Vite serve both native and web.

/**
 * Intent-based link prefetching using mouse trajectory prediction.
 *
 * Uses ray-casting to detect when the user is moving toward a link,
 * scoring by distance + perpendicular offset. Winner-takes-all prevents
 * over-fetching when multiple links are in the path.
 *
 * Key features:
 * - Batched IntersectionObserver for efficient rect measurement (300ms intervals)
 * - Velocity smoothing to filter jitter
 * - Prefetched links removed from future checks
 * - Debounce between consecutive prefetches
