# Grep-based verification of the hard, checkable rules in this skill that
# `npm run lint` / `npm run build` do not catch on their own — a wrong
# react-router-dom import, a hardcoded basename, an inline style prop, a
# stray lightning/*-or-@wire import, or leftover template boilerplate can
# all lint and build clean while breaking at runtime or shipping unfinished
# branding.
#
# Usage: verify-rules.sh <file-or-dir> [<file-or-dir> ...]
#   Pass the specific files you edited, or the bundle's src/ directory (and
#   its index.html) to check everything.
#
# Exit 0 if no violations are found.
# Exit 1 with every violation listed (rule + matching file paths) if any
# are found — fix them before considering the task complete, even if lint
# and build passed.
