異界裂空

Retrofuristic sci-fi, stylized realism, impossible sky phenomena, neon megacity, epic atmosphere. Lone explorer in white tactical cloak with glowing visor. Nighttime city. A thin glowing line appears across the sky from horizon to horizon. The line widens into a gigantic crack. Through it, another universe becomes visible: upside-down cities, alien stars, and impossible geometry. Buildings begin floating toward the crack. The Scout races through streets as gravity bends upward. Camera flies toward the opening. Entire skyscrapers drift through the rift into the other universe. Final wide shot: two realities overlap in the sky, with cities hanging upside down above the Earth like reflections in a cosmic mirror. SFX: dimensional hum, cracking sky, wind distortion, cinematic boom.
