    // Bucket: A step up, handling larger datasets or more complex lexical processes.
    // Barrel: Substantially greater capacity, signaling robust intermediate processing or models.
    // Vat: The pinnacle of processing—handling massive, industrial-scale lexical or sentential progression.
    // Tank: For even larger or more advanced processes.
    // Reservoir: Denoting a vast storage or synthesis capability.
