SNN (Style Name Notation) provides a foundational, rule-agnostic naming system for identifying game styles in abstract strategy board games. This gem implements the SNN Specification v1.0.0 with a modern Ruby interface featuring immutable style name objects and functional programming principles. SNN uses case-consistent alphabetic names (e.g., "CHESS", "SHOGI", "XIANGQI" for first player; "chess", "shogi", "xiangqi" for second player) to unambiguously represent both style identity and player assignment. As a foundational primitive with no dependencies, SNN serves as a building block for formal style identification across the Sashité ecosystem. Format: All uppercase OR all lowercase alphabetic characters only (no digits, no special characters). Ideal for game engines, protocols, and tools requiring clear and extensible style identifiers.
