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
