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. Four-character Chinese text "木良久日" rendered as the hero calligraphic inscription on softly fibrous xuan paper, with each character carrying fully loaded sumi ink behavior: dense carbon-black pools at decisive stroke entries, irregular wet edges bleeding delicately through paper fibers, translucent charcoal-grey passages where the brush runs dry, and fine separated bristle filaments at tapering exits. Preserve the supplied characters exactly. The paper ground is warm aged ivory with faint deckled-fiber grain, scattered pale tan specks, and restrained water-stain halos. Behind the inscription, a sparse pale-grey ink wash suggests distant mountain contours dissolving into blank paper, kept low-contrast so the black brushwork remains dominant. A few microscopic ink droplets and fractured dry-brush flecks appear near the most energetic stroke endings. Add one small vermilion cinnabar seal impression as a secondary accent, its worn edges and imperfect stamped pigment contrasting the fluid black ink. Soft diffuse daylight reveals paper tooth, absorbed ink bloom, and luminous unpainted negative space; no digital outlines, no uniform black fill, no glossy surface.
