  "prompt": "Use case: ads-marketing, cinematic science-fiction concept illustration.\nAsset: full-bleed 16:9 homepage key visual for the original game Stellar Echoes / 群星回响. Generate one coherent theatrical science-fiction poster image WITHOUT any text, logo, captions, diagram panels or watermarks. This is a promotional interpretation of existing designs, not a new design proposal.\nReference image 1: the original GUIHANG mothership design, its recognizable identity must be preserved: a massive long industrial ark, faceted blunt prow, warm ivory armor, slate-blue structure, restrained faded brick-red identification panels, low bridge, exactly two rectangular lateral hangar mouths, aft propulsion banks. It must feel lived-in, monumental and beautifully engineered, not a generic pointed battleship or flying city.\nReference image 2: the three original carried craft and their shared design language: compact nonhumanoid explorer with sensor booms, a heavy hornless humanoid sentinel with low recessed head/ivory armored shoulders/shield and rifle, and a squat multi-arm harvesting workframe with material container. Use these three distinct silhouettes sparingly at plausible very small scale near the mothership's ports, as readable secondary accents, not giant superhero figures.\nReference image 3: human daily life aboard the ark, warm amber practical light, layered industrial habitation thresholds, plants, worn ivory and slate surfaces. Translate this emotional home-like quality into a narrow foreground interior observation threshold in the lower-right of the composition: a few tiny calm human silhouettes and a modest plant behind glass, watching their shared world. Do not portray the interior as a cutaway hole in the mothership hull. This is a foreground viewpoint from a separate visiting craft or station, no architectural canon implied.\nScene: immense quiet outer space, the pale blue-grey limb of a beautiful ringed gas planet filling the upper right, sweeping thin rings and sparse icy particles creating depth, far distant modest orbital structures. The original ark is the dominant subject at center-right, moving gently toward left foreground, lit by cold pearl reflected light and a thin golden sunrise rim. Warm inhabited window points and the two lit ports reveal people live here. Show immense scale and silence, discovery rather than a battle.\nComposition: ultra-wide cinematic, highly art-directed, main ship entirely legible from a three-quarter port-side angle across the middle-right. Preserve a clean dark blue-black negative-space area across the LEFT 35 percent for live HTML title typography, and keep the top 12 percent comparatively quiet for a site navigation. Strong diagonal depth with elegant restrained contrast. Lower edge transitions into deep midnight shadow so live HTML captions remain readable. Ship must not be cropped out on desktop. Do not put a huge bright subject in the left typography area.\nStyle: premium contemporary science-fiction game key art, intricate painterly hard-surface rendering, mature Japanese space-opera design sensibility integrated with tangible industrial hardware, subtle analog film texture, extraordinary material and light, emotionally expansive. Not a collage, not a technical drawing, not photobashed UI. Palette: midnight navy, desaturated pearl ivory, petrol blue, warm amber inhabited lights and tiny brick-red accents. Cosmic scale balanced with intimacy and hope.\nConstraints: no explosions, combat, lasers, giant faces, fighter jet carrier, cathedral spires, impossible organic tentacles, oversaturated neon, random text or existing franchise symbols. Do not add a new giant external centrifuge ring to the reference ark. Quiet human civilization and the unknown are the emotional subject.\n",
