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. Render the exact Chinese text “人生得意须尽欢” as the dominant calligraphic element, painted in deep sumi ink on handmade xuan paper with visible long fibers, faint deckled grain, and uneven warm ivory absorbency. Each character carries forceful wet-to-dry brush behavior: saturated near-black pools at initial pressure points, dense glossy ink cores, soft charcoal transitions through broad turns, and separated bristle filaments at lifted stroke endings. Allow irregular ink bloom to feather delicately into the paper fibers, with a few tiny airborne ink droplets near the most energetic directional sweeps. Preserve luminous paper negative space between strokes and inside character counters. Behind the text, introduce a restrained pale grey ink-wash landscape: distant low mountain silhouettes dissolving into diluted water, a narrow river-like wash, and sparse mist created by untouched paper grain. Add a small vermilion cinnabar seal impression with worn edges and uneven pigment deposit as a secondary accent. Use natural side illumination across the paper surface, revealing subtle wrinkles, absorbent fibers, dried ink ridges, and translucent diluted washes. No digital-clean outlines, no uniform black fill, no decorative Western elements; every mark should retain brush pressure, water load, and irreversible hand-painted variation.
