EUI delivers an application interface over HTTPS without HTML, CSS or JavaScript: the server sends a tree that is already resolved, in a compact binary encoding, and a native client lays it out and draws it on the GPU. This gem is the server half in Ruby — the encoder, the session, the content-addressed asset store, the signed manifest, and a component model where a view is a hash and a handler changes state.
