High-Contrast Focus Blur Typography Art

Create a high-contrast digital artwork featuring the word '[WORD]' in bold lowercase signature stylized font. Place the word centered on a plain white background. Apply a sharp focus effect to the center letters '[LETTER/S]' only, while progressively blurring the surrounding letters outward with a radial motion blur. The blur should be strongest at the first and last letters and gradually reduce toward the center, creating a visual focus effect. The text color should be solid black.
