Four iconic space missions displayed in golden blueprint frames

16:9, do this for 4 famous space missions: void main() {      string[] subjects = {"[SUB_1]", "[SUB_2]", "[SUB_3]", "[SUB_4]"};          // Setup Materials     vec3 bg_mat = pure_black_matte();     vec3 ui_ink = unlit_metallic_gold(depth: 0.0);     vec3 sculpture_mat = pbr_metal(brass, chrome) + refractive_glass(IOR: 1.5);          // Setup Viewports (2x2 Grid)     vec4 canvas = clear(bg_mat);     for(int i=0; i<4; i++) {         vec2 quadrant = get_grid_cell(i, columns: 2);                  // Render 3D Centerpiece         mat4 reliquary = build_intricate_model(subjects[i], sculpture_mat);         render_to_cell(quadrant, reliquary, lighting: museum_spotlight);                  // Render 2D UI Overlays         vec3 wireframe = generate_blueprint(subjects[i]);         vec3 text_data = infer_specs_and_quotes(subjects[i]);         draw_hud(quadrant, wireframe + text_data, material: ui_ink);     }          // Add Global Text     draw_hud(header, "[THEME] CORES", material: ui_ink);     fragColor = canvas; }
