# File attachment size limit for the AI chat panel (Optional, default: 10 MB)
# This controls the server-side JSON body limit. Base64 encoding adds ~33% overhead,
# so a 10 MB server limit supports files up to ~7 MB.
# The client-side pre-check threshold is hardcoded in ChatPanel.tsx → MAX_ATTACH_MB (default 4 MB).
# If you raise this, also raise MAX_ATTACH_MB in the client to match.
