PS: In your environment file you have
\setuplayout[
  header          = 0pt,
  footer          = 0pt,
  headerdistance  = 0pt,
  footerdistance  = 0pt,
  top             = 1.125in,
  topdistance     = 0pt,
  bottom          = 1.125in,
  bottomdistance  = 0pt,
  leftedge        = 0.85in,
  rightedge       = 0.85in,
  height          = fit]
ConTeXt will silently ignore all of this. You must not have space
between keywords and options. Write this as
I've been using context, on and off, for 5 years and I did not know
that!
Does anyone know if there is a way to get context to stop when it sees
an unknown option, instead of silently ignoring it?
The way this is dealt with in the core is by specifying options using 
\c!header, etc. This has two advantages: First we get a multi-lingual 
interface for free. Second any typos in the keys are caught. This does not 
catch "mistakes" like giving an new option to a command, for example 
specifying headstyle=something to \setuphead (headstyle is valid for 
\setupitemgroup, but not for \setuphead).

There is, however, no way of catching "errors" like

height= fit,

Here context thinks that height is set to " fit" (with the space), and 
this does not match any of the cases in the code, so is ignored.
