超宽屏构造裂谷和世界末日场景提示（JSON 格式）

{
  "intent": "A monumental, vertiginous composition of a continental-scale tectonic rift where a massive, deep-sea ocean current terminates at a perfect geometric precipice, cascading into a bottomless atmospheric void filled with tiered cloud layers and lightning.",
  "frame": {
    "aspect_ratio": "21:9 ultra-widescreen",
    "composition": "The frame utilizes a vanishing point perspective that follows the literal edge of the world into infinity. The top-left quadrant is dominated by the dark, churning Atlantic-scale ocean, while the right and bottom sections reveal the terrifying scale of the vertical drop into a hazy, multi-layered cloud abyss.",
    "style_mode": "Raw_photorealism with hyper-accurate fluid dynamics and atmospheric Rayleigh scattering to establish immense scale."
  },
  "subject": {
    "identity": "The ruins of an ancient, megalithic limestone bridge, four kilometers in width, which once spanned the gap but now ends abruptly in a jagged, fractured edge at the precipice.",
    "wardrobe": "A tiny, barely visible research vessel is positioned near the edge of the falling water, providing a critical sense of gargantuan scale through size comparison.",
    "placement": "The ruined structure is anchored into the basalt bedrock of the 'continental shelf' that forms the world's end."
  },
  "environment": {
    "location": "The 'Great Sheer'—a non-Euclidean geographic terminus where the planet's crust simply ceases, revealing a vertical cross-section of geological strata before descending into the troposphere.",
    "atmosphere": "Extreme atmospheric depth, with visible 'cloud falls' where moisture from the ocean drop condenses into secondary weather systems thousands of meters below the primary sea level.",
    "weather": "Violent updrafts from the abyss creating spray-vortices at the edge, while the distant depths of the rift are illuminated by internal, cloud-to-cloud lightning."
  },
  "camera": {
    "sensor_format": "Large format digital (Phase One IQ4 150MP), optimized for maximum per-pixel detail and wide dynamic range in the deep shadows of the chasm.",
    "lens": "14mm ultra-wide-angle rectilinear lens to exaggerate the perspective distortion and the sheer scale of the verticality.",
    "camera_position": "A cantilevered perspective, positioned several hundred meters out into the void, looking back toward the edge of the world and the falling ocean.",
    "aperture_depth_of_field": "f/11 to ensure the texture of the falling water in the foreground and the distant geological strata are captured with clinical sharpness."
  },
  "lighting": {
    "type": "Harsh, high-altitude sun positioned at a 45-degree angle, creating deep, well-defined shadows within the craters and crevices of the vertical cliff face.",
    "color_temperature": "5400K (neutral daylight), with a significant shift toward 12000K (deep sky blue) in the shadowed depths of the abyss due to atmosph
