DESIGN BRIEF: horizontal-band fusion for Delhi headphone commute — how do circle headphones, smartphone rectangle, and train window band read in Warli white-line grammar without breaking monochrome or importing a tarpa spiral as rush-hour energy? Three registers mirror classical wall stacking: skyline above, vehicle hero middle, street walkers below. What we refused: perspective subway tunnel, route-map text, multicolor advertising, dance ring. What we kept: centre-window headphone hero with phone gaze-down, flanking seated commuters, decorative triangle borders framing vehicle band, street-level walkers with briefcase rectangle, dot bottom border. Light density (~45%) keeps ochre visible in sky register.
