+echo "Replace deprecated sainnhe.everforest VSCode extension with reesew.everforest-theme"
+
+# Background:
+#   The original "sainnhe.everforest" extension is no longer maintained — its
+#   upstream repo (https://github.com/sainnhe/everforest-vscode) was archived
+#   by the author, so it receives no updates or fixes.
+#   "reesew.everforest-theme" is a maintained fork of that same extension,
+#   published from https://github.com/reese/everforest-vscode, and is the
+#   replacement we now ship in themes/everforest/vscode.json.
+
+
+# For each VS Code variant, uninstall the old extension and re-apply theme if the
+# current Omarchy theme is everforest (which will install the new extension automatically).
