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 "Katja" becomes the sole ink-mark on warm ivory xuan paper, with the paper’s long fibers, faint deckled grain, and scattered natural flecks visible across the ground. Preserve the supplied letterform silhouette while rendering its strokes through fully loaded sumi ink: dense blue-black pools at heavier stroke entries, smoky charcoal transitions through narrower passages, and translucent dry-brush exits where individual bristle hairs separate across the absorbent paper. Fine capillary feathering softly blooms into the fibers around wet sections without obscuring the text. A few controlled micro-droplets and pale diluted ink-wash traces surround the most energetic brush movements, leaving broad quiet paper margins. Use directional raking light to reveal the paper texture and slight matte variation in dried ink, with no gloss, no digital-clean vector edges, and no extra words. The composition should feel like a single deliberate calligraphic gesture, balancing saturated ink mass against luminous untouched negative space.
