“机型”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: '机型' laser-cut from thick warm birch plywood, the two CJK characters occupying the full visual weight of the frame, placed on a dark raw-timber workshop surface with visible grain running beneath. Directional warm amber key light raking from low-left at a shallow 18-degree angle — sharp precise shadow lines tracing every kerf edge, material slab depth rendered as a 6mm shadow face along the right and lower edge of each character. The cut face reveals honey-gold birch cross-grain at the kerf cross-section; a dark charred seam borders every stroke boundary with mathematical precision, the char line thin and consistent as a single scorched millimeter. Complex interior strokes of the CJK characters retain their structural bridge tabs — thin birch material connections arching over enclosed counter spaces, each tab a deliberate fabrication feature catching amber light across its narrow face. Negative space between strokes shows the dark timber backing surface as real air gaps. Background: raw dark-timber workshop surface with subtle warm grain texture fading to near-black at the frame periphery. Surface scattered with faint fine birch sawdust residue at letter edges. Nothing else in frame — just the cut plywood piece, the dark surface, and the raking warm light.
