[kenancasey]

Is your feature request related to a problem? Please describe. No.

Describe the solution you'd like As a user, I'd like to read an intro/preamble paragraph to help set the context and build motivation for praying the upcoming prayers.

Describe alternatives you've considered I considered showing this as a modal popup (dismissable) or as static text above the cards in the prayer deck. Follin did not prefer either of those options.

Additional context This is a feature request from Follin for which she has already written content (but it hasn't been finalized and delivered).
