Create a finished, portrait-format tattoo design on a clean pure-white field. Center the exact rune sequence “ᛚᛁᛊᚨ” in one horizontal line as the unmistakable focal point. Preserve these four characters in this exact order and render them as sharply legible Elder Futhark-inspired runes: tall, narrow, blade-cut geometry, straight strokes only at 0°, 45°, and 90°, hard vertices, no curves or rounded corners. The runes are solid pure matte black, with no texture, gradients, shadows, highlights, or glow. Build a balanced, vertically elongated Norse insignia around the lettering: a spare angular shield outline with restrained, mirrored interlocking knotwork and small forged-metal details. Keep every ornamental stroke angular and subordinate to the rune sequence; leave clean white breathing space between the frame and glyphs. Render the surrounding frame as dark iron and cold granite with a few aged-bronze details and tiny dark-amber accents. A narrow cold highlight from upper left and restrained warm forge light on the outer metal accents suggest forged permanence without spilling onto or altering the black rune faces. Use crisp tattoo-flash linework, confident black contours, limited tonal shading confined to the frame, and a strong readable silhouette. White remains open around the design. No extra words, letters, numbers, symbols that resemble text, mockup skin, or background scenery.
