rendered as expressive Western brush script lettering with fluid connected strokes. Visible bristle texture with authentic thick-to-thin pressure variation — thick downstrokes, thin upstrokes, just like a loaded calligraphy brush. Ink slightly wet and glistening. Natural ink pooling at stroke starts, feathered dry-brush ending trails. Warm off-black ink on visible surface texture. Hand-crafted artisan energy with real brush imperfection. 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 brush-script medium, the thick-to-thin pressure variation and the ink wetness. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as fluid connected brush-script strokes with thick downstrokes, thin upstrokes, wet pooling at starts and feathered dry-brush trails in warm off-black ink. COLOR PRIORITY: keep the font's own colors if specified; otherwise warm off-black ink on a textured surface. Create a finished Japanese calligraphy-inspired training poster on warm, lightly fibrous washi paper, with a restrained palette of warm off-black ink, smoky gray, and a small muted vermilion seal-like accent with no extra writing. Render the exact text 「忍者になるための訓練」 in one prominent, carefully spaced line, centered across the upper-middle of the composition; keep every character clear, correctly formed, and legible. Let the connected Western brush-script treatment feel freshly written by hand, with strong thick-to-thin pressure, subtle bristle texture, glossy wet highlights, ink gathering at stroke beginnings, and a few delicate dry-brush trails. Below the words, show a lone ninja training in a quiet bamboo courtyard at dawn: a dark, simple silhouette balanced in a low stance on worn stone, one hand extended, with a short practice staff resting nearby. Thin bamboo shadows angle across the paper-like ground, and a faint wash of mist opens into generous negative space behind the lettering. The figure and setting stay understated and secondary, preserving the text as the clear focal point. Use a close, intimate composition, soft natural side light, and sparse, confident details; no additional lettering, symbols, or decorative clutter.
