Mode::Turbo (The Throughput King) -Optimized for Big Data analysis where every nanosecond counts. -* **Technology**: **Vectorized Depth Skipping**.

Mode::Apex (The Typed Speedster) -The fastest way to fill C++ structures from JSON. -* **Technology**: **Direct-Key-Jump**. Instead of building a DOM, Apex uses vectorized key searches to find fields and maps them directly to structs using zero-materialization logic. - -### 3. Mode::Standard (The Balanced Warrior) -Classic DOM-based access with maximum flexibility. -* **Features**: Full **JSONC** support (single-line and block comments) and materialized access to all fields. - -### 4.
