Whistler Tonalist Nocturne (Style-Only, Image-Conditioned)

Re-render this image as a James McNeill Whistler Nocturne, in the visual register of Nocturne in Black and Gold, Nocturne in Blue and Silver, and Arrangement in Grey and Black. Extreme tonal restriction: the entire picture occupies a narrow band of values within a single hue, typically a deep blue-green dusk, a silver-grey twilight, or a brown-gold riverine nocturne. Paint applied as thin atmospheric washes in liquid oil and turpentine, the surface wiped and re-glazed multiple times, brushwork erased into pure tone. Subject reduced to silhouette and suggestion, no rendered detail, no modeling, no internal description, just the dark mass against the slightly less dark ground. Selective tiny dabs of high-key accent in the deepest darks: a yellow lamp, a spark of gold from a firework, a single white catch on water, distributed sparingly like a musical accent. Composition flat and Japanese-influenced (ukiyo-e), often with a strong off-center vertical or horizontal compositional bar, the influence of Hokusai and Hiroshige absorbed and Westernized. Aspect: contemplative, evening, the senses dialed down to the threshold of perception. Frame implied: thin gold leaf with a Whistler butterfly mark suggested at the corner, do not render the butterfly legibly. No on-canvas text, no signature, no studio watermark. Preserve the subject, pose, and composition of the source image exactly, change only the medium and rendering.
