Use case: photorealistic-natural. Create ONE finished standalone photographic website background for the Fire & Ember collection. Real observational outdoor fire photography at night, quietly beautiful and cozy. The photograph should feel captured rather than arranged. Physically plausible irregular combustion: transparent thin flame edges, pale straw-yellow hottest tongues over deeper orange bases, occasional faint blue only right at a burning wood edge, ember light confined to cracks, matte black char and friable gray-white ash. Flame motion has slight natural softness while wood and ground retain genuine detail. Mild real sensor grain in shadows, gentle lens contrast and photographic highlight rolloff; do not recover every shadow. Blacks are deep but not a cutout background: faint contiguous ground or air gives spatial grounding near the subject. Only the fire illuminates the immediate surroundings, with irregular occlusion shadows and rapid natural falloff. No fill lights, no perfectly circular pool of light, no HDR, no artificial glow cloud, no sharpened orange outlines, no smooth CGI surfaces, no plastic wood, no symmetrical teepee logs, no uniformly arranged stone ring, no bonfire spectacle, no excessive particles. Restrained charcoal, soot, muted copper, ochre and pale golden flame. Protect the specified large quiet negative space for later website typography. Full bleed. No people, hands, buildings, camping gear, stars, moon, text, lettering, logo, UI, watermark, borders or collage. Required framing: 21:9. Scene: Ultrawide horizontal 21:9. Actual sparse wood-fire embers lifting on warm air against near-black night. The very bottom RIGHT corner contains a barely visible small cropped edge of a real burning log with faint flame, providing a physical source. About twelve irregular tiny glowing carbon flecks and short faint motion trails rise through a narrow region in the RIGHT third, dispersed unequally, most barely lit, two brighter orange points. Natural convection trajectories rise and drift slightly left; trails are short and varied from a roughly 1/60-second exposure, never long fireworks arcs. No symmetrical spray, no particles across entire canvas, no bokeh circles, no gold glitter dust. Left two thirds and upper left completely quiet black, at least 90 percent darkness. Real restrained spark photograph.
