Create a clear educational urban-design infographic in Persian about the importance of facade continuity and street-edge design in Iranian cities, using the real urban character of Khak Sefid neighborhood in Tehran as the example. One wide scene divided into two visually connected halves: on the left, a chaotic street edge with mismatched building setbacks, exposed blank walls, unfinished facades, tangled overhead wires, irregular signage, broken sidewalks, scattered parking and weak pedestrian space; on the right, the same neighborhood reimagined with a coherent human-scale street wall, aligned building fronts, shaded arcades and shopfronts, continuous sidewalks, trees, benches, controlled signage, warm brick and plaster materials inspired by Iranian urban architecture, active pedestrians and safer public space. Use a subtle central transition arrow showing that better facade design improves urban identity, pedestrian comfort, safety, social interaction and visual order. Add large, highly legible Persian typography integrated into the graphic: title «اهمیت جدارهسازی در شهرسازی ایران»; left label «جدارهی گسسته و بیهویت»; right label «جدارهی پیوسته و انسانمحور»; bottom callouts «هویت شهری»، «آرامش و امنیت»، «تعامل اجتماعی»، «خوانایی خیابان». Make the Persian text correctly spelled, crisp and readable, with no invented Latin words.
