After Dark Arts Poster

Create a polished original nighttime arts festival poster as full-frame flat print artwork. Exact large Chinese headline: 夜里有光. Make the four Chinese characters perfectly readable in warm ivory, running across the upper third with elegant generous spacing. Below, a small amber doorway opens inside an enormous midnight-blue paper rectangle; three thin curved amber lines drift out like quiet music, creating depth without literal illustration. Exact small English footer: AFTER DARK / ARTS NIGHT. Midnight blue, charcoal, ivory and amber palette, subtle paper grain and soft ink edges, dramatic negative space, one focal glow, editorial sophistication. No extra words, no logos, no border or photographed frame. Vertical 3:4 composition. Generate one complete original image at native 2K resolution, with clear fine detail and no watermark, signature or unintended extra text.
