“Hi”是使用 FontVibe AI 创作的手写体文字效果。细腻的胡桃棕墨水手写体，写在暖米色纸上，字母流畅相连、回环柔和，旁边是蘸水笔和墨水瓶。

Intimate writing-desk light field — warm directional light arriving from a 30–45-degree upper-left angle, the quality of morning window light filtering through gauze or the halo of a brass desk lamp; this raking light travels across the paper surface at low angles, revealing fiber tooth and ink body depth simultaneously. Secondary warm fill from the right side at 20–25% key intensity preserves intimate shadow without eliminating it. The substrate is always textured paper: hot-press cotton rag, aged parchment, smooth vellum, cream laid stock, or cold-press watercolor paper — paper surface grain and fiber are visibly revealed under raking light, with a subtle warmth yellowing toward the edges. Ink sits proud on the surface: a subtle wet sheen at maximum-density stroke points, matte dry finish at hairlines; at dramatic stroke termini, micro-droplets of ink may cling to paper fiber. Atmospheric details: floating paper dust motes caught in window light rays, faint ink bloom halos around dense stroke endpoints. Color temperature: warm amber-sepia throughout the background environment and paper surface; slightly cooler clear-white at the central text zone for luminous contrast. Background beyond the writing surface: soft warm bokeh or warm shadow — never competing with the foreground. Letter surface color and material are defined entirely by each font's own prompt_core — this style provides only the writing-desk light field, paper substrate environment, and ink-on-surface atmosphere. When no specific material is defined by the font: morning window light from upper-left at 35 degrees on warm cream cotton laid paper, paper fiber texture clearly visible under raking light, soft amber fill from the right at 25% intensity. A single sheet of warm cream hot-press cotton rag paper fills the frame, its fiber texture and laid lines revealed under sharp morning raking light arriving from the upper-left at roughly 35 degrees. 'Hi' in casual handwriting sits boldly on the paper, the two letters large and generous, walnut-brown ink sitting proud on the cream surface — thick downstrokes holding a subtle wet sheen, the crossbar and curve carrying the spontaneous energy of a first word dashed off to a friend. The ink at stroke endpoints shows micro-droplets clinging to paper fiber. A well-loved ballpoint pen rests beside the letters at a relaxed angle, its clip slightly worn, its tip still touching the paper as if just lifted mid-thought. A small torn corner of an envelope peeks into the lower edge of the frame. Paper fiber and chain-line texture are clearly visible under the raking light. Soft warm amber secondary fill from the right at 20% key intensity preserves intimate shadow depth without eliminating it. The paper edges warm toward amber, a gentle vignette. Warm bokeh softens everything beyond the writing surface — the whole scene carrying the feeling of a quick, genuine, handwritten greeting.
