// Drives the JSON / base64 / binary-plist decoders in
// `src/icloud/photos/enc.rs` through both shapes:
//   - parse the input as a JSON Value and call every decoder on the
//     resulting structure (covers JSON-shape edge cases),
//   - wrap the input as a base64 ENCRYPTED_BYTES payload inside a synthesized
//     JSON envelope (drives the bplist parser without making libfuzzer
//     discover the JSON wrapper itself).
