Single illustration, nighttime convenience store exterior, warm fluorescent glow spilling onto sidewalk, stylized indie cartoon look, clean contours, flat cel colors, limited palette with candy-like accents (warm yellow light, teal shadows, soft pink highlights, charcoal blacks), subtle halftone texture in shadows, paper grain, two teens outside: one leaning on bike, the other holding a small snack bag, expressive faces—half amused, half defensive—like mid-friendly argument, store interior hinted with simplified shelves as rectangles, strong silhouette readability, crisp spot blacks in hair and jacket folds, poster-like composition, no panels, no captions, no speech balloons, no readable brand text
