Dark minimalist ghost mascot brand poster AI Image Prompt

Create a minimalist cinematic brand poster in a dark monochrome palette, showing a cute small white ghost mascot figurine sitting on rumpled black velvet fabric. The ghost has a smooth rounded dome body, soft scalloped base, tiny side flippers, glossy black circular eyes, a small black X-shaped mouth, and a small ornamental droplet-shaped knob on top of its head. Place the mascot on the right half of the composition, softly lit from the upper right with gentle specular highlights and deep shadows, shallow depth of field, premium product-photography feel, 16:9 horizontal format. On the left side, add exactly two text elements: a three-line Japanese quote in white handwritten-style type reading {argument name="quote" default="たまに、\n全部どうでも\nよくなるよね。"}, positioned upper left with generous line spacing, and a bold spaced uppercase brand wordmark reading {argument name="brand name" default="GHOSTCO."} near the lower left. Keep the background nearly black with subtle fabric texture, moody but adorable, calm, melancholic, modern Japanese character-brand advertising aesthetic.
