Dust of Deep Space Cosmic Calligraphy Poster

Full prompt

A celestial typography poster design showcasing the primary headline in custom cosmic script calligraphy, featuring starlight-sharp terminal points and orbital flowing strokes.

The background is an infinite dark purple gradient enriched with stardust particles, flowing interstellar gas clouds, and sparkling starlight glints. Includes the clean English secondary title 'Dust of Deep Space' and decorative orbital path text arranged in a distinct visual hierarchy, modern and philosophical 3:2 landscape ratio, no signature, no watermarks, no brand logos.
