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 low oblique photograph of the last coals of a wood fire. Very low discontinuous band of dark charcoal and gray ash stretches only across the central third close to bottom edge, between 40 and 75 percent across. A handful of tiny dim orange ember gaps appear irregularly under the ash; most of the wood is completely black. One thread of soft barely visible smoke escapes and disappears. No flame, no flying sparks, no bright horizon line. Top 80 percent is almost entirely black and silent; ends of the ash bed fade naturally into unlit ground rather than a graphic line. Natural detail, subdued real exposure, unhurried warmth, no lava texture or glowing rock field.
