“Tim_”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 close-up: 'Tim_' laser-cut from thick warm birch plywood, letters and trailing underscore character filling a generous portion of the frame, resting on a dark raw-timber workshop surface with visible open grain running beneath. Directional warm amber key light raking from low-left at a shallow 12-degree angle — fine crisp shadow lines tracing every kerf boundary, material slab depth rendered as a 6mm shadow face along the right side of each form. The cut face reveals honey-gold birch cross-grain with subtle annual ring variations; a thin dark char seam precisely outlines every letter edge and the clean straight kerf of the underscore bar. The 'i' counter dot sits as a floating island of backing surface, its bridge tab a deliberate design feature catching a sliver of amber sidelight. Background: near-black dark craft-studio timber surface fading softly toward the frame edges, warm grain texture at low opacity. The underscore reads as an integral typographic element — same material slab thickness, same char-edged kerf precision. Nothing else in frame — just the cut piece, the raw surface, and the raking warm light.
