几何线描星座插画

海报版式插画，四个虚构星座以精确几何线描表现，背景为深午夜靛蓝。整体为柔和 2x2 网格，每格一个星座：跃兔、扬帆船、长颈鹤、盘蛇。每颗星是一个浅金色小实心圆，由等粗的暖白细线连结，互不交叠。每个星座外有一圈精细等距圆环作为天图窗口，每十五度一处刻度。靛蓝背景并非纯色，带极轻颗粒与零星淡灰微点表示次要星辰。四象限中央有一个小型几何风向罗盘。每个星座下方为简洁现代衬线体的小标签，原文： 「LEPUS NOVA」、"NAVIS"、「NAVIS」、「GRUS LONGA」。底部一行细脚注 「几何线描星座插画」。无发光、无镜头光晕、无伪星云——严格图形化，近乎建筑制图，如一张深思熟虑的信息海报。情绪沉静、学究、略带诗意。

A poster-format illustration showing four imagined constellations rendered as precise geometric line art on a deep midnight-indigo background. Each constellation occupies one quadrant of a soft 2x2 grid: a leaping hare, a sailing ship, a long-necked crane, and a coiled snake. Every star is a small filled circle in pale gold, connected by single-weight thin warm-white lines that never overlap. Around each main constellation, a perfectly drawn fine circle frames it like a celestial chart window, with delicate tick marks every fifteen degrees. The background indigo is not flat: it carries a barely-there grain and a few extra scattered micro-dots of pale grey representing minor stars. Centered between the four quadrants sits a small geometric compass-rose motif. Tiny restrained labels in a clean modern serif beneath each constellation read exactly: "LEPUS NOVA", "NAVIS", "GRUS LONGA", "SERPENTIS". A single slim line of footer text reads "observed from a quiet rooftop, winter". No glow, no lens flare, no fake nebulae — strictly graphic, almost architectural, like a thoughtful infographic poster. Mood is contemplative, scholarly, slightly poetic.
