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. Traditional Chinese ink-brush treatment for the exact text “生日快乐”. Deep black sumi ink carries dense wet cores, with irregular brush-hair fringes along every contour, pooled glossy ink at decisive stroke entries, and translucent charcoal dry-brush breaks through the departing stroke tails. The text dominates with clear celebratory visual rhythm, preserving generous breathing room between characters. Fine xuan rice-paper fibers remain visible through thin ink passages; subtle capillary bleed softens selected edges into the warm ivory paper. A pale misty ink wash spreads outward behind the characters in diluted grey, punctuated by a few controlled micro-splatter droplets from energetic brush lifts. Add a small vermilion cinnabar seal impression as a restrained decorative accent, its carved texture slightly broken by paper grain. No digital-clean outlines, no uniform black fill, no glossy printed typography. Soft raking daylight reveals paper tooth, absorbed ink, feathered fibers, and the wet-to-dry tonal transitions across each painted mark.
