Title: Clarified when reactivity works

After reading the Reactivity section for the first time, I was under the slight impression that a reactive context would be sufficient for triggering changes. E.g. if the name in the fragment example were set not from `Session`, but from a global, it could be surmised that the HTML fragment would still be automatically updated if the global variable changed.

This small patch tries to make it clearer that reactivity requires *both* a reactive context and a reactive data source.
