# Fix 404 for /_next/static/* by copying .next/static into standalone.
# Run on the server when the app loads but CSS/JS chunks return 404.
#
# Use when:
# - You built on the server (npm run build) and never copied static into standalone, or
# - The tarball was created without the build_nextjs_artifact.sh copy step.
#
# From project root on server:
#   sudo bash scripts/fix_nextjs_static.sh
