Constant MAX_BLOB_SIZE 

pub const MAX_BLOB_SIZE: usize = _; // 104_857_600usize

Maximum size of a blob in bytes (100 MiB).

Decoders should reject blobs larger than this limit to prevent memory‑exhaustion attacks. This is not enforced at the type level (i.e., Blob::new(data) will accept any Vec<u8>), because legitimate use‑cases (e.g., scientific datasets) may require larger blobs. However, any decoder that processes untrusted input must respect this bound and return VctrlError::CorruptedData if the encoded size exceeds MAX_BLOB_SIZE.

use libvctrl_handler::MAX_BLOB_SIZE;

// The reference decoder in libvctrl_core uses this limit:
// if data_len > MAX_BLOB_SIZE { return Err(…); }
