Copy each source file into components/. Keep the filenames and their relative imports together. Then use the example below. Use the runtime and file types listed on this effect’s usage notes. The example uses the common @/ import alias; use a relative import if your project has no alias.

"use client";
import { SeamErosion } from "@/components/material-effects/material-components";

// Copy the listed files into components/, preserving both subdirectories.
// Use React 19.3, CSS Modules and the font variables below.
// pnpm add @fontsource/instrument-serif@5.3.0 @fontsource/space-mono@5.3.0
// Sediment: copy the licensed local image to public/material-wave-a/ as well.
