“危险高压”是使用 FontVibe AI 创作的激光切割文字效果。粗壮无衬线大写字母从暖色桦木上激光切出，切口边缘焦黑、木纹清晰，凸立在深色胡桃木板上，琥珀色侧光。

Precision fabrication aesthetic: text exists as physical cut material — not rendered, not painted. The laser kerf is the only boundary: mathematically exact edges, zero roughness. MATERIAL SURFACE RULES: — Wood: warm grain on letter face (birch honey or dark walnut); charred dark seam along every kerf edge; cross-grain cross-section at cut face. Gentle warm transmission through thin sections. — Acrylic: glassy-smooth kerf edges scatter light as luminous halos — frosted emits soft white-blue edge glow; clear creates prismatic edge-light. Face stays matte or polished. — Metal: bright machined cut face against brushed exterior. Raking light reveals mechanical precision and directional grain. — Paper/Organic: bone-clean cut edges casting hairline shadows on backing. Maximum filigree detail preserved. FABRICATION LAWS (all materials): — Enclosed counters (O,D,B,P,R,A) retained by structural bridge connections — thin material tabs turned into design features. — Material thickness always visible as dimensional depth: each letter is a physical slab. — Negative space is real air or backing material showing through. — No added outlines, glow effects, or drop shadows — the kerf edge is the only boundary. FORBIDDEN: graphic fills, smooth gradient fills on letter faces, extruded 3D depth. When no specific material is defined by the font: default lighting — warm amber side light raking from low-left, deep warm shadow on right and behind, dark warm-brown craft-studio background. Industrial safety placard fabricated from a single 8mm slab of brushed stainless steel, laser-cut with the exact Chinese text “危险高压”. The characters dominate the frame as real through-cut material, with negative space revealing a matte near-black powder-coated steel backing panel behind every aperture. Each laser kerf has mathematically clean boundaries: bright silver machined cut faces, narrow heat-darkened seam at the outermost edge, visible slab thickness, and crisp cross-sectional depth under raking illumination. Fine horizontal brushing runs continuously across the metal faces, interrupted only by the precise cutouts. Where enclosed internal spaces require retention, narrow engineered bridge tabs remain visibly integrated into the fabrication, matching the steel material and preserving every character’s structure. Low amber-white side light skims across the brushed surface from a shallow angle, catching the machined cut walls and producing hairline physical shadows on the black backing; no graphic outline, no glow, no printed ink, no extruded treatment. Surrounding surface is a dark industrial electrical-cabinet panel with restrained screw heads and faint scuffs, kept subdued behind the sharply resolved laser-cut warning text. Macro product-photography clarity, real material texture, precision workshop fabrication.
