动漫奇幻风格主视觉项目

Create a cinematic anime key visual and concept-art presentation board for a fantasy adventure titled {argument name="project title" default="Codex & GPT-Image-2"}. The main image fills the upper portion: a vast ruined stone causeway high above the clouds at night, leading toward a circular observatory-like sanctuary with towers, antennas, and a glowing mechanism at the summit. A vivid aurora arcs across a star-filled sky over distant mountain ranges. Three travelers stand on the bridge in a triangular composition. In the center foreground, a pale white-haired girl in a flowing white robe and cape walks toward the viewer, holding a staff with a red ring ornament; her expression is calm and mysterious. On the left, a tall woman with very long dark purple hair and a dark cloak turns slightly away, looking toward the structure. On the right, a red-haired young man in a brown coat stands with his back angled to the viewer, carrying a large dark weapon. The bridge is weathered, cracked, and lined with glowing cyan inlaid paths and runic strips, with stone pillars and balustrades on both sides. Add large title typography in the upper right, with a smaller Japanese subtitle beneath it reading {argument name="subtitle text" default="灰銀のアウロラ"}. Add a small Japanese tagline in the lower left reading {argument name="tagline text" default="旅は、記憶の先へ続いている。"}. Beneath the hero image, place a horizontal strip of detailed monochrome and muted-color concept sheets showing exactly 8 grouped design panels: 1 white-haired heroine full-body costume turnaround sheet, 2 white-haired heroine face-expression sheet, 3 heroine accessories and gear sheet, 4 purple-haired woman outfit turnaround and detail sheet, 5 red-haired man outfit turnaround and weapon sheet, 6 architectural exterior elevation sheet of the observatory, 7 architectural interior and structure reference sheet, 8 circular mechanical diagram sheet. Along the bottom, place exactly 4 environment thumbnails: 1 ruined mountain road landscape, 2 icy-blue bridge or aqueduct environment, 3 distant hilltop approach to the sanctuary, 4 towering cathedral-like interior hall. Overall style: premium anime game art pitch board, highly detailed, painterly, dramatic lighting, cool blue and cyan palette with white stone and subtle orange title accents, polished layout, epic fantasy sci-fi atmosphere.
