3D minimalist studio

Create a 3:4 vertical minimalist digital brand poster with an absolutely pure black background. In the center of the image, place an oversized, thick, rounded, tilted continuous handwritten 3D word "edit", the letterforms like a soft inflatable silicone tube connected in one stroke, with natural thickness variation, letters interweaving but still clearly legible; the main body occupies most of the width horizontally, positioned vertically slightly above center, leaving wide black negative space. The color transitions continuously from left to right: deep purple and electric blue into magenta and pink, then to red-orange, golden yellow, bright cyan-green and mint cyan; the color band flows along the curved surface of the letterforms rather than being rigidly segmented by letter. The surface is covered with very fine glitter sand particles and tiny point highlights, the contour edges softly glowing, with a tactile feel combining matte velvet and fine sand spray; the thick rounded cross-section has realistic light and shadow shaping, with mild subsurface scattering in places, no mirror-like plastic feel. In front of the center of the wordmark, overlay a short and delicate semi-transparent black rounded action capsule, with slight frosted glass, fine gray stroke and soft shadow: on the left is an original white abstract folded-corner graphic, in the center the text "Open in genvizu", on the right a small button "Launch". The capsule size is restrained, not covering the entire letterform. Overall sharp, modern, clean, like a still frame from an experimental motion design studio. No real platform names or logos, third-party trademarks, QR codes, watermarks, extra elements, colored background, floating particles or garbled text.
