 **How It Works**:
-1. Script parses topology dictionaries to identify all port connections by priority
+1. Script analyzes the topology's FPP model to find each instantiated component's async input ports, internal ports, and async commands by priority
 2. For each component and priority, finds maximum serialized size across all port types
 3. Adds `DATA_OFFSET` (priority + port ID overhead) to each size
 4. Generates namespaced constants for use in configuration
