Create a dark, high‑contrast poster with a {argument name="style" default="moody, underground club aesthetic"}. The composition features a monochrome portrait of a young woman from the chest up, shot from a slightly low angle for attitude and power. She wears large over‑ear headphones and reflective round sunglasses with {argument name="lens color" default="warm amber‑gold"} lenses that stand out vividly against the black‑and‑white portrait. One hand is raised near her head, the other near her chin, creating a dynamic, expressive pose associated with music immersion. Behind her head is a large flat {argument name="shape color" default="golden‑yellow"} circular shape, like a spotlight, creating a strong focal point and visual contrast. The background is deep black with subtle grunge textures, dust, scratches, and poster‑wear imperfections, giving it a raw, printed‑flyer feel. Use 4:5 aspect ratio.
