Let's get this started with problems in the codex! Rooms which have multiple requirements as well as preclude other floors (i.e.: the shop floors)simply have too much going on to fit flavor text without bumping up against the edge of the page. The worst offender is the Shady Shop, which... well, see for yourself.
The Conflagrator's flavor text is having line break issues.
Everything else looks good on a first pass, I'll post more if I catch something later.
