Raw Normal View History

/* NOTES
=====
Initially this uses <NavLink> from react-router-dom, but it doesn't work:
1. It interferes with nested <a> inside <a> and it's difficult to preventDefault/stopPropagation from the nested <a>
2. isActive doesn't work properly with the weird routes that's set up in this app, due to the faux "location" to make the modals work and prevent unmounting
3. Not using <Link state/> because it modifies history.state that *persists* across page reloads. I don't need that, so using valtio's states instead.
