# The npm tarball carries only the compiled server. Its runtime dependencies
# are resolved by npm at install time, which the Portage sandbox forbids, so
# they ship as a second distfile generated offline from this exact release.
# Upstream publishes no npm-shrinkwrap.json; --before is what pins the
# transitive tree (normally >= 7 days in the past; 2026-09-28 was a deliberate
# same-day refresh, requested by the maintainer), and the resolved tree
# is recorded in node_modules/.package-lock.json inside the tarball:
#   tar xzf ${MY_P}.tgz && cd package
#   npm pkg delete devDependencies scripts
#   npm install --omit=dev --ignore-scripts --no-audit --no-fund \
#       --before=2026-09-28
#   tar --sort=name --mtime='2026-09-28 00:00:00Z' --owner=0 --group=0 \
#       --numeric-owner --format=gnu -cf - node_modules \
#       | xz -T1 -9e > ${PN}-node_modules-${PVR}.tar.xz
# Every bump must regenerate and upload this tarball, and redo the LICENSE
# survey from node_modules/.package-lock.json.
