Struct FaceLookup 

pub struct FaceLookup {
    pub bbox_json: String,
    pub file_path: String,
    pub hash: String,
}

The single-row query face_image_bytes needs before it can do any image work, split out so a caller holding a shared/locked Connection (the axum server serializes every request on one Mutex<Connection>) can release that lock immediately after this cheap lookup, instead of holding it for the entire decode/crop/resize/encode/cache-write below, which otherwise fully serializes every thumbnail request behind the lock, turning a many-thousand-singleton library into one thumbnail at a time.
