+# fix-npmrc-all-repos.sh — Standardize .npmrc + pnpm-workspace.yaml
+#                          across all ByteLyst repos
+# ─────────────────────────────────────────────────────────────
+#
+# Problem: repos hardcode "gitea.bytelyst.com" in .npmrc, which
+#          breaks on corp network (TLS-intercepting proxy).
+#
+# Solution:
+#   1. Replace hardcoded Gitea URL with env-var-based URL
+#      using $GITEA_NPM_HOST (set by switch-network.sh).
+#   2. Add workspace link to ../learning_ai_common_plat/packages/*
+#      so @bytelyst/* resolve locally (no registry needed).
+#   3. Add link-workspace-packages + prefer-workspace-packages.
+#
+# Usage:
+#   bash scripts/fix-npmrc-all-repos.sh          # dry run
+#   bash scripts/fix-npmrc-all-repos.sh --apply   # actually write files
+#
+# ─────────────────────────────────────────────────────────────
