futuristic concrete wall 3d model

Create a single continuous futuristic industrial concrete wall based closely on the reference image. Large flat rectangular wall, pale gray/off-white concrete, minimalist SCP Foundation-style facility aesthetic. Keep the entire wall solid and continuous: NO door, NO doorway, NO opening, NO hole, NO window, NO gap, NO split sections. Add recessed rectangular panel seams, thin vertical grooves, small circular bolt details, and a muted dark olive-green horizontal strip running across the middle. At two structural sections, extend several thin vertical green strips downward into small raised concrete blocks. Add subtle lower recessed panel lines and base trim. Clean symmetrical hard-surface geometry, slightly weathered concrete, no deformation or curves. No floor, ceiling, environment, text, logos, signs, furniture or people. Front orthographic view, perfectly straight-on, no perspective distortion, isolated on a dark gray background.
