# P7 (2026-10-04): cross-platform golden table.
# For every level, compare tools_pc/golden/<level>/linux/ against
# tools_pc/golden/<level>/win/ with framediff.py in both modes:
#   --exact --tol 2          -> per-pixel share over tol (the rendering delta)
#   default (structural)     -> worst grid-cell dmean, nonclear delta, phash
# Prints one line per (level, frame) plus a per-level verdict.
#
# Path-agnostic: the repo root is the parent of this script's directory
# (tools_pc/), so it can be invoked from anywhere; no absolute path, no
# '~', no machine default.
