Generate a monochrome single-color SVG icon. Simple line art with a consistent stroke weight of 2.5px on a 100×100 viewBox. All strokes must be expanded/outlined into closed filled paths (no open strokes). Use even-odd fill rule. Rounded line caps and joins with a 3px corner radius on sharp corners. Minimal detail — the icon must be instantly recognizable at 16×16px. No fills, no gradients, no shadows, no textures, no text, no labels. Centered on canvas with ~10% padding on all sides. The visual style should match Apple SF Symbols like `cup.and.saucer`, `wineglass`, or `fork.knife` — clean, geometric, friendly, and professional. [Style constraints] — Draw a rocks glass (old fashioned glass) seen from the side. Short, wide cylindrical tumbler with a flat heavy base. The width should be roughly equal to the height, giving it a squat, sturdy appearance. Walls are straight or taper very slightly outward toward the rim. Include a subtle horizontal line about 1/3 from the bottom to suggest the thick glass base. No ice, no liquid, no garnish. The silhouette should read as clearly short and wide — a low, chunky tumbler.. Emphasize a cohesive composition, cinematic lighting, vivid details, strong subject focus, and layered depth.

The image shows a black and white drawing of a glass of water on a white background. The glass is filled with a clear liquid, likely water, and is outlined in black.
