Create a highly stylized, monochrome coloring page dominated by stark, high-contrast black and white line art. The focal point is a scruffy, golden retriever puppy nestled amongst ancient, moss-covered trees. The puppy is mid-leap, its tail enthusiastically wagging, just slightly off-center, towards a small, weathered wooden bridge spanning a rushing, dark river. Behind the dog, a jagged, snow-capped mountain range rises dramatically in the background, its peaks softened by a hazy, overcast sky. The scene is set within a slightly overgrown, shaded forest clearing. Focus on creating a whimsical, slightly melancholic atmosphere. Line art should be incredibly crisp and precise, with strong, clear outlines defining every detail of the dog’s fur, the tree branches, and the bridge’s structure. Employ a limited palette of deep blues, greys, and muted greens in the background to create visual depth. The overall impression should be one of quiet, gentle wonder and a touch of nostalgia. No color is used; purely line art. Think early 20th-century illustration style, but with a modern, clean aesthetic. Emphasis on detail in the dog's expression – a slight tilt of the head and a hopeful gaze. A slight vignette effect, pulling the viewer’s eye towards the puppy. --- Let me know if you'd like me to refine this further!, black and white coloring page, lowbook style, line art, monochrome, uncolored, no shading, no grey, no fill, white background, outline only
