# --- Driver 2: Primal Sensates+ (PS+) ---
# The visceral driver of the Drive-Box. PS+ does not reason; it FEELS.
# It reads the endocrine array and the priors store, then emits arguments --
# weighted, embodied claims about reality -- never logical propositions.
#
# Foundation modules are sourced as-is (repo-root-relative paths).
