an abstract cosmic portal of pure neon energy, glowing violet and indigo, surrounded by a faint star-field on a deep-space backdrop. camera: slow push-in toward the portal, very slight parallax on star-field. physics-based volumetric light rays spill outward, silky plasma tendrils ripple and fold. style: ultra-clean CGI, synthwave + cyber-noir aesthetic, high-contrast, HDR, lens bloom. no text, no logos, no watermarks.
