Ruined Sci Fi Manga Page

Goal: Create a black and white sci fi manga page showing a ruined futuristic city after a catastrophe, with cinematic wide shots and empty dialogue bubbles for later lettering. Canvas: Vertical manga page, portrait orientation, clean white page border, high contrast monochrome ink and grayscale screentone, detailed debris textures, dramatic cloudy sky, no color. Layout: Use exactly 4 horizontal panels stacked from top to bottom, separated by thick white gutters. Panel 1: A very wide establishing shot filling the top third of the page. Show a devastated megacity with collapsed skyscrapers, broken elevated roads, rubble, dust, and a stormy sky split by bright light. Include floating chunks of wreckage in the sky. Add exactly 2 blank white manga speech bubbles: one tall rounded polygon bubble at the upper left and one larger rounded polygon bubble at the upper right. Panel 2: A narrow panoramic panel beneath it. Low angle view of a towering damaged building wall and a dark sky with a levitating rock or debris chunk. Add exactly 1 blank white speech bubble on the right side. Panel 3: A narrow action detail panel. Close up of one black combat boot stepping onto cracked ground, with small stones and debris floating around it. Add exactly 1 small blank white speech bubble on the left. Leave a large empty white rectangular gutter/space on the far right of this row, as if the panel does not extend across the full page. Panel 4: A large final panel occupying the bottom portion. Rear view of a young girl and a small robot facing the ruined city and apocalyptic sky. The girl stands on the left, wearing a dark jacket, short shorts, thigh high black socks, and sturdy boots, with short dark bobbed hair. The robot stands to her right, squat and cylindrical with a domed head, small side arms, treads, vents, and mechanical details. The background shows broken buildings framing the scene, rubble in the foreground, floating debris in the sky, and a bright crack of light through dense clouds. Subject details: The main human character is {argument name="character name" default="a silent young girl"}, with {argument name="hair style" default="short dark bobbed hair"}, wearing {argument name="outfit" default="dark jacket, short shorts, thigh high socks, and black boots"}. The companion is {argument name="robot companion" default="a small cylindrical treaded robot with a domed head"}. The setting is {argument name="ruined city setting" default="a collapsed futuristic megacity under a stormy sky"}. Visual style: Serious seinen sci fi manga, painterly ink wash, dense architectural detail, gritty rubble, dramatic perspective, atmospheric haze, heavy blacks, textured grayscale, cinematic composition, no sound effects, no visible lettering inside the bubbles. Constraints: Exactly 4 panels and exactly 4 blank speech bubbles. Keep all speech bubbles empty white with black outlines. Do not add captions, titles, watermarks, logos, page numbers, or extra characters.
