Constant MAX_A7P_DECODED_BYTES 

pub const MAX_A7P_DECODED_BYTES: usize = _; // 1_048_576usize

Hard cap on the DECODED .a7p payload accepted by profile.import_a7p. Real files are a few KiB; this exists purely as a resource bound (the request envelope’s own MAX_REQUEST_BYTES already caps the base64 text).
