プロンプト全文（英語）

Educational infographic map poster of the annual night-sky constellation observation guide, front-view flat presentation. Layout: one large circular polar star chart at the center showing the northern and southern celestial hemispheres as two nested dials, surrounded by four seasonal quadrant panels for spring, summer, autumn and winter, each listing 5-6 visible constellations with small glyph icons of their mythological shapes (Ursa Major, Orion, Cassiopeia, Scorpius, Pegasus, Cygnus). A month ring around the chart marks the best observation window for each constellation, with a small legend for magnitude brightness dots and meteor-shower dates. Color system: deep navy background (#0B1D3A), golden star points (#F4C95D), soft teal lines (#4ECDC4) for constellation strokes, coral (#FF6B6B) for highlighted seasonal markers and soft white for labels. Typography: elegant serif display for the title, clean sans-serif for data labels, clear three-level hierarchy. Background: subtle noise texture with faint dotted coordinate grid and a soft radial glow behind the chart. Data feel: observatory reference poster with precise degree ticks. Lighting: even flat illumination, luminous glow from the chart itself, no harsh shadows. 4k
