Today when attempting to use the tool, I noticed that clicking Generate Keys did nothing, and when checking the console, it showed the error generateX25519Identity is not defined.

After further investigation, I noticed that the age.wasm module was taking a few seconds to finish downloading (it's 871 kB, just for reference).

I believe it would be helpful to make it clear that the module hasn't been loaded yet by preventing the user from clicking anything, and/or maybe showing a temporary loading text.
