“Scan”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. Workshop flat-lay: 'Scan' laser-cut from a single slab of smooth frosted acrylic — each letterform a physical object with measurable 6mm thickness sitting on a dark brushed concrete studio surface. The frosted material catches a cool blue-white LED strip light raking from the low-left, scattering luminous prismatic halos along every precision kerf edge — the cut boundary glowing from within the material itself, no added glow effects, only the physics of acrylic edge-scatter. The letter face reads as a soft matte cloud-white against the brilliant luminous rim. The counter of the letter 'a' is retained by a hairline structural bridge tab — a deliberate fabrication detail catching its own sliver of light. Material slab depth visible as a bright machined cut face on the right-angle kerf wall, contrasting the brushed face. The dark concrete surface beneath reflects faint cool light back into the undersides of each letter. Background recedes to near-black at frame edges, isolating the cut piece as the single focal object. Render quality: product photography, octane render, 8k, shallow depth of field, cool-toned ambient, high-contrast chiaroscuro.
