linear issue
THIS IS A PoC
added a third button to login with a SIWE prompt that opens landing, signs a message, and registers with username: address, password: signature
obviously that is not the final form of registration/login
originally, i had added another react navigation screen to the account modals. from a UX perspective, i like the idea of matching the other sign in experiences instead of presenting a full modal screen. it's definitely ugly tho.
i think the endgame is a bottomsheet modal that pulls up to about ~half the screen, that way we can re-use it anytime we need to sign messages.
