# CloserApp — automated theme-mismatch scanner (Pass C pre-check)
#
# ⛔ CLAUDE: You may improve this script whenever you discover a new failure mode
# for light/dark theme mismatches. Keep the script self-contained, runnable from
# the project root, and write findings to stdout + SCAN_OUTPUT. Update this header
# with any new patterns or exclusions you add.
#
# Usage:
#   ./scripts/theme-scan.sh > /tmp/claude-theme-scan-$(date +%Y%m%d).md
#   ./scripts/theme-scan.sh --json   # (future improvement — machine-readable)
