Can you store USD in MetaMask?

Excuse me, as a professional practitioner in the field of cryptocurrency and finance, I'm curious about the capabilities of MetaMask. Could you clarify whether MetaMask supports the storage of traditional currencies, specifically US dollars (USD)? My understanding is that MetaMask is primarily a wallet for Ethereum-based tokens and cryptocurrencies. However, with the evolving landscape of decentralized finance, I'm wondering if there's a way to bridge the gap between traditional finance and the crypto world through MetaMask or similar platforms. Could you elaborate on this?
