/**
 * next.ts — Next.js config helper.
 *
 * webpack does not treat `.wasm` as an asset by default, so the standard build
 * variant needs a one-line rule. `withOpenSlide` injects it (and chains any existing
 * `webpack` function), turning the manual recipe into:
 *
 * ```js
 * // next.config.js
 * const { withOpenSlide } = require('@computationalpathologygroup/openslide-js/next');
 * module.exports = withOpenSlide({ /* your config *\/ });
 * ```
 *
 * Note: you still need the COOP/COEP headers (SharedArrayBuffer is required). See
 * INTEGRATION.md. If you use the `/single` variant, you do NOT need this helper — the
 * `.wasm` is inlined there.
 *
 * Typed structurally so the package does not depend on `next` at build time.
