# The scene parity test on a build box (the Mac runs no headless browser: standing rule, 7 October 2026). Carries the files the
# test needs to the box under this lane's prefix, runs tools/scene/parity.mjs there and prints its report; the box's own
# Playwright build and Chromium (root installed the libraries on 7 October 2026, 14:5x UK) do the rendering.

#   tools/scene/parity-remote.sh [--box N] [--out <dir>]     default box 2; --out fetches the frames and the report back
#
# Where it runs: a box named by ~/.config/igneum/build-server[-N] (build@<ip>); on a machine with no box file but a local
# Playwright (a CI runner that is itself a box) it runs parity.mjs in place; with neither it prints a skip line and exits 0,
# so a plain GitHub runner stays green while every box-side and Mac-side gate renders for real.
