Does Cardano use sharding?

Cardano is a blockchain platform that aims to address scalability issues faced by other cryptocurrencies like Bitcoin and Ethereum. It employs a unique architecture consisting of two layers: the Settlement Layer and the Computation Layer. While Cardano has explored sharding as a potential scaling solution, its primary focus has been on its layered approach. As of my knowledge cutoff, Cardano's implementation of sharding remains in development or theoretical stages.
