レトロフューチャー軌道モーテル看板と環状惑星の宇宙壁紙

Vertical 9:16 phone wallpaper of a retro-futuristic orbital motel sign floating beside a ringed planet, chrome boomerang shapes, atomic starbursts and grainy 1960s space-age texture, warm neon tubes glowing against deep cosmic blue, sign anchored low with vast clean star field above, coral, teal and cream palette, optimistic roadside-in-space nostalgia, no text, no logo, no watermark, no borders.
