turns out that using the old stylesheet was breaking the row-fluid stuff that
is step (0).  now happily works, and i can get to watching the rest of the
changes bloom!
finally finished typing in, and playing with, the entire part 1.
didn't do any transitory check-ins, but played a lot with the chrome visual
inspector and just refreshing on chrome/ipad/iphone.

tried to maintain my own mini-flourishes.  the next check-in will likely
remove them, as that's what I think is needed for submission of part 1.
