File size too large. Maximum size is 5MB.

Error message

File size too large. Maximum size is 5MB.

What it means

Size guard in the logo upload endpoint: the fully read upload body exceeds the 5MB cap. Large logos bloat config storage and slow the unauthenticated image-serving path, so oversized files are rejected after the size check rather than stored.
