 * Returns an IPX instance for processing images.

 *   server origin, which avoids filesystem path issues on serverless platforms
 *   (e.g. Vercel) where the build-time publicDir no longer exists at runtime.
 * - Dev mode: uses local filesystem storage for instant local edits.
 *
 * @param domain - Allowed CDN domain for external media mode.
 * @param originUrl - Current request origin (e.g. `https://mysite.com`). When
 *   provided in non-external mode, enables the same-origin HTTP storage path.
 * @returns An IPX handler when the optional dependency is available, otherwise `null`.
 * @example
 * await getIpx('cdn.example.com', 'https://example.com')
