-> **Token-optimized JSON compression for Large Language Models.** Reduces tokens by up to 23% on uniform data. ASON achieves **+4.94% average** reduction vs JSON, while Toon averages **-6.75%** (worse than JSON).
+> **Token-optimized JSON compression for GPT-4, Claude, and all Large Language Models.** Reduce LLM API costs by **20-60%** with lossless compression. Perfect for RAG systems, function calling, analytics data, and any structured arrays sent to LLMs. ASON 2.0 uses smart compression with tabular arrays, semantic references, and pipe delimiters.

+## ✨ What's New in ASON 2.0?
+
+- ✅ **Sections** (`@section`) - Organize related data
+- ✅ **Tabular Arrays** (`[N]{fields}`) - CSV-like format with explicit count
+- ✅ **Semantic References** (`$email`, `&address`) - Human-readable variable names
+- ✅ **Pipe Delimiter** (`|`) - More token-efficient than commas
+- ✅ **Advanced Optimizations** - Inline objects, dot notation in schemas, array fields
+- ✅ **Lexer-Parser Architecture** - Robust parsing with proper AST
+
