# PATH: /scripts/fix_paths.sh
# VERSION: 03.05.00
# BRIEF: Replace Windows-style path separators with POSIX separators in text files.#
# Purpose:
# - Normalize path separators in text files to forward slashes (/).
# - Intended for CI validation and optional remediation workflows.
# - Skips binary files and version control metadata.
# - Preserves file contents aside from path separator normalization.
#
# Usage:
#   ./scripts/fix_paths.sh
