Design an ultra-minimalist icon logo for a climbing guide brand called "crag.guide". Focus: simple, bold, highly recognizable symbol. Style: flat, geometric, reduced to essential shapes only. Concept options: - abstract cliff/crag silhouette - single continuous climbing route line - carabiner simplified to basic geometry - negative space forming a rock face or ascent path Constraints: - no text (icon-only) - no gradients - no shadows - no textures - max 2 colors (prefer black/white or black + subtle accent) Shape: - compact, square-friendly - strong silhouette, readable at very small sizes (favicon/app icon) Line work: - consistent stroke weight or solid fills only Aesthetic: - modern outdoor-tech - clean, scalable vector design
