Seedance 2.0 Waiting Queue Poster

Create a clean square promotional poster with an isometric miniature 3D diorama on a warm off-white background. At the top, place huge bold rounded sans-serif headline text reading headline text, split across 2 lines, with a vibrant left-to-right gradient from blue and violet through magenta to orange. Below the headline, show a long serpentine queue of tiny stylized people waiting in front of a row of minimalist white cube buildings; include 12 visible white building units receding into the distance, each with simple rectangular windows and doors, and one prominent open doorway on the right. The crowd should contain dozens of small diverse figures in casual clothing, arranged in a winding line that creates depth, with one purple-uniformed staff member near the open doorway gesturing people inside. Use soft studio lighting, shallow depth of field, subtle shadows, glossy clean surfaces, and a premium tech-advertising look. At the bottom center, place a colorful circular gradient app-style icon followed by the black wordmark brand name. Keep the composition airy and minimal, with the headline dominating the upper half and the queue scene occupying the middle and lower area.
