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 ceremonial handwritten proclamation on aged cream laid paper, its surface filling the frame with clearly visible cotton fibers, faint chain lines, and warm amber darkening at the deckled edges. Render the exact text "一息尚存，不忘救國" as the sole hero inscription, with dominant visual weight and breathing room around the inked characters. Dense walnut-brown iron-gall ink sits physically above the paper: saturated brush pools carry a restrained wet sheen, dry-brush edges break into individual fibers, and tiny ink blooms feather outward at the heaviest terminals. Morning raking light enters from the upper-left at 35 degrees, skimming across the ink relief and paper tooth; a weak amber fill from the opposite side preserves deep, soft-edged shadows. A narrow band of cooler daylight crosses the central paper field, increasing contrast around the inscription while the surrounding paper shifts toward sepia. At the paper perimeter, restrained historical writing-desk details remain softly out of focus: a dark wooden brush rest, a small porcelain ink dish, and the blurred edge of a red cinnabar seal impression. Dust motes drift through the angled light beam. No digital gloss, no pure black ink, no clean white background; tactile paper grain, irregular ink absorption, and hand-made writing evidence remain visible throughout.
