Minimalist ink calligraphy signature.

Generate a minimalist ink typography visual centered on a specific theme, transforming keywords, phrases, or names into an abstract signature-like structure: the main body of the image is composed of a few dark brushstrokes. The brushstrokes do not pursue a neat printed feel, but should show the force, pauses, reserved white (flying white), dry/wet density, and rough edges of rapid brush movement, creating an Eastern calligraphy character that is both recognizable and imbued with a personal mark. The visual center has well-balanced density, focused in the middle of the image, surrounded by a large amount of bright, clean, transparent negative space, making "emptiness" part of the mood. Maintain density differences between brushstrokes, using short dots, vertical lines, long arcs, and diagonal sweeps to carry rhythm, making the reading path like the natural rhythm that disperses after a breath-held brushstroke. Colors are extracted from the theme's materials and emotions, maintaining a high-brightness clean background, a small amount of dark structural brushstrokes, and extremely low decorative density; the overall style should be bright, quiet, pure, and restrained. The final effect should be like a handwritten title with an independent personality, both a spiritual guide for the text and close to an abstract symbol, avoiding standard fonts, calligraphy copybooks, dense posters, or decorative illustrations.
