Create a clean production-ready SVG logo mark suitable as a header icon, app icon, and favicon. An abstract, balanced emblem built from simple geometric shapes with a symmetrical silhouette that remains legible at small sizes. Use thin-to-medium strokes with rounded caps and joins. Color palette: copper #B86A38 and brass #C7A15A for the main mark; ember accent #D97B2F sparingly for highlight. Provide an optional graphite/dark version using #1F1A17. Style: flat vector, no gradients or textures, crisp edges, scalable down to favicon size (16x16). The design should avoid text, be clean, modern, and production-ready. Output as a single, self-contained SVG file; ensure robust readability at small scales and compatibility with both light and dark UI.
