Edit the supplied TERKINSTEIN artwork into a square firmware boot-screen asset. The source image is the authoritative logo: preserve the exact TERKINSTEIN lettering, letter order, distinctive heavy-metal contours, central forked tall strokes, thorn/vine frame, and trailing outer strokes. Preserve the original white artwork on a pure solid black background. Crop away surplus empty black margins and scale/reposition the entire existing mark to fit the square canvas with a modest black safe margin on every side; keep every outer tip visible. Center the artwork. Do not invent new artwork, change the logo design, alter the word, add typography, add a tagline, add symbols, add borders, add color, or add gradients. It must ultimately work at 240 by 240 pixels on the M-VAVE FM-1 LCD, so retain clean bold white forms and subdued antialiased edges; simplify only very fragile doubled outline detail if essential at that tiny size, while retaining the source identity. Deliver a crisp square opaque PNG suitable for exact downsampling to 240 by 240 pixels.
