Sigma Grindset, Black-and-White, Black-Coffee Register

Render in the sigma-grindset video-edit meme register, the stark monochrome dawn-window aesthetic. Pure black-and-white treatment, occasionally one muted desaturated grey-blue or warm-sepia tonal wash, never full color. High contrast: hard shadow on one side of the face, bright highlight from the implied window-light on the other. Line work invisible, the effect is photographic-illustration, not cartoon. Skin rendered with hard shadow modeling, dramatic, slightly grainy texture as if filmed on a phone in low light then processed through a high-contrast filter. Eyes are intense, gaze fixed forward or into the distance, the look of grindset-discipline. Mouth closed, flat, serious, never smiling. If hands are visible, render them holding an implied small dark cup shape, abstracted black-coffee mug, no detail, no logo, just a flat dark round-bottom shape with steam suggested by two or three faint curling lines. Background is a flat dark grey or black with a single bright rectangle suggesting a window, the window itself rendered as a flat near-white rectangle with no detail beyond a hint of cool blue at the edge suggesting dawn light. The whole image carries the register of solitary-disciplined-grind, the visual cliche of the sigma-edit. Cinematic, deliberately overproduced, the seriousness pushed slightly past the point of credibility. No words, no letters, no captions, no text-overlay, no logos, no watermarks, no named hate-symbols, no real-person likeness. Preserve the subject, pose, and composition of the source image exactly, change only the medium and rendering to this sigma-grindset monochrome register.
