Cold brushed titanium surface with precision-machined edges and micro-etched detail lines. Cryogenic blue-white edge illumination — cold internal glow emanating from letter seams, the photonic quality of light bending near a gravitational event horizon. Hard vacuum atmospheric quality: zero ambient scatter, maximum edge contrast, each hairline stroke reading as a laser-cut threshold between titanium and void. Surface texture: aerospace-grade matte titanium with subtle anisotropic grain direction. The visual language of Christopher Nolan's hard science fiction — monumental, minimal, cold, inevitable. Forbidden: warm tones, organic textures, soft edges, lens flare colour. "404" rendered as a monumental hard-science-fiction error marker, each numeral formed from cold brushed aerospace-grade titanium slabs with precision-machined bevels, micro-etched calibration marks, recessed seam channels, and subtle anisotropic grain. Cryogenic blue-white light burns from the internal seams and cut edges, creating laser-sharp thresholds between metal and absolute black void. A single distant star from the upper-left casts hard directional illumination: exposed titanium planes bleach to near-white, while recessed grooves fall into black with no ambient fill. Behind the numerals, a vast ringed gas giant emerges from deep vacuum, its desaturated blue-gray cloud bands barely visible and its thin rings catching the same cold stellar light. Far below, a colossal orbital station silhouette with rectilinear docking arms provides scale, its tiny operational lights restricted to icy cyan-white. Sparse hard vacuum stars remain pin-sharp; one narrow cyan-white anamorphic streak crosses the scene without colored flare. No haze, smoke, dust, explosions, warm light, organic texture, or soft bloom. Ray-traced 8k cinematic render, maximum edge contrast, silent deep-space operational environment.
