Review finding (Wren): fetch_avatar buffered the full response before checking MAX_AVATAR_FETCH_BYTES, so a missing or dishonest Content-Length could consume unbounded network/memory. Now preflights content_length() and streams with a running cap check that rejects before appending any chunk that would cross 10 MiB — same contract as media_download.rs. Accumulator boundary extracted for unit testing. Co-authored-by: Tyler Longwell <tlongwell@block.xyz> Signed-off-by: Tyler Longwell <tlongwell@block.xyz>
