# canvas TSX. Thin shell-out so /design:handoff doesn't have to spin up Bun
# from the orchestrator side.
#
# Usage:
#   bin/handoff.sh <canvas-abs-path> [designRoot]
#
# Output (stdout, line 1): JSON {"dest":"...","files":N,"deps":M}
# Exit code 0 on success, 2 on any failure (with reason on stderr).
