rendered in Chinese ink brush calligraphy style. Letterforms painted with a fully loaded sumi ink brush — deep black ink, visible bristle marks along stroke edges, wet ink pooling at stroke starts, feathered dry-brush trailing ends. Authentic ink density variation: thick rich black cores fading to grey at thin passages. Rice paper texture visible behind. Traditional Chinese calligraphy energy — each stroke confident, intentional, irreversible. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the sumi ink medium, the bristle and ink-density behavior and the rice-paper ground. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as deep black sumi brush strokes with visible bristle marks, wet ink pooling at stroke starts and feathered dry-brush trails on rice paper. COLOR PRIORITY: keep the font's own colors if specified; otherwise rich black ink fading to grey at thin passages. The rendered text "難以滿足" formed in saturated sumi ink across absorbent handmade xuan paper, with a restless sequence of forceful black marks and interrupted breathing space between characters. Dense carbon-black pools collect at initial pressure points, breaking into charcoal-grey veils where the brush lifts and changes direction. Every stroke carries exposed brush filaments, irregular frayed edges, dry-brush skips, and thin translucent passages where warm paper fibres remain visible beneath the ink. Small ink droplets and fractured specks radiate from the most abrupt turns, while a diluted ink wash expands behind the text like uneven water staining, fading from smoke grey into bare ivory paper. The paper ground has visible long fibres, faint deckle creases, scattered age freckles, and soft areas of absorbed moisture. Maintain the supplied letterform shapes precisely, using the ink treatment as the dominant material behavior. High-resolution macro paper texture, natural pigment granulation, subtle ink bleed following the paper grain, restrained vermilion seal fragments and a single faded red stamp impression as peripheral calligraphic artifacts. No digital-clean outlines, no uniform black fill, no glossy surface, no modern graphic effects.
