A precision aerospace test chamber viewed straight-on, built from matte graphite wall panels, recessed seams, small amber status LEDs, and a narrow instrument console running along the lower edge. The central display area is a clean, uninterrupted deep-charcoal panel with generous negative space. Render the exact text "30 seconds" as two centered lines: "30" large in the upper center, "seconds" directly beneath at smaller scale, with disciplined vertical spacing and a shared center axis. Keep the text completely clean, isolated, and unobstructed against the panel. Around the outer perimeter, include faint technical grid lines etched into the architecture, tiny unlabeled calibration ticks, and dim recessed light channels, all kept low contrast so they never compete with the text. A cool white overhead strip light creates controlled illumination across the chamber surfaces; a restrained amber indicator glow appears only in the distant panel recesses. Subtle airborne dust is visible only in the side light near the frame edges. Frontal orthographic composition, crisp high-resolution industrial photography, deep focus, controlled blacks, restrained graphite, steel-blue, and amber environment palette. No additional readable words, numbers, symbols, logos, interface labels, or foreground objects.
