Detailed Description

The wire metadata for one rendered ASCII frame. width and height describe the terminal grid, original_size and compressed_size bound the encoded text, and checksum detects corruption; flags carry frame-specific options. The variable text follows this fixed prefix and is owned by the packet storage until decoding completes.

ASCII frame packet structure (Packet Type 2)

Contains complete ASCII art frame with metadata for terminal rendering. Used for both client->server (camera input) and server->client (mixed output) transmission.

Note: ASCII frame data follows this header in the packet payload.; If compressed_size > 0, data is zstd compressed.; Format: char data[original_size] or compressed_data[compressed_size]
