# Build a room into gen/ — thin wrapper over build.py.
#
# Usage:
#   ./ctrl/build.sh              # standalone -> gen/standalone/
#   ./ctrl/build.sh amar         # amar       -> gen/amar/
#   ./ctrl/build.sh all          # every room under cfg/
#   ./ctrl/build.sh models       # only regenerate models
#
# build.py holds the logic; this exists so `make build` has exactly one
# script to call, and so the room name is a plain argument.
