Learn them. You can split your seed words into two or more "fake" sets on coldcard. It also reconstructs them for you into your real set. Put on a passphrase. Save your passphrase securely. Use derived entropy to construct a multisig. That way you only have to secure one seed. Lots of ways. I think most people have a single device with a passphrase. If your seed is found, they still can't get your stash.
