Struct Engine 

pub struct Engine<E: ScriptEngine> { /* private fields */ }

Statically dispatched owner of a script backend.

Deref is the phase-zero bridge for the existing DOM bootstrap and public Boa context callback. New execution entry points belong on ScriptEngine. Backend-specific document bootstrap uses the explicit backend accessors.
