+Portable Cursor IDE prefs live under macOS Application Support and are managed:

+```
+Library/Application Support/Cursor/User/settings.json   → theme, composer, update track
+Library/Application Support/Cursor/User/keybindings.json → cmd+i → composerMode.agent

 - **Per-tool settings** removed in the AI-native overhaul (Claude `settings.json`,

 - **Ephemeral/sensitive runtime state** under `~/.cursor`, `~/.claude`, `~/.codex`
   (auth, caches, history, project state) is not in the repo — the Cursor
   `modify_` script preserves it on the machine but never commits it.
