+- **Version** lives in the active manifest (`version`) and any browser-specific manifest you ship. Do not duplicate it in `scripts/config.js`.
+- **Display name and default shortcut copy** for the settings page come from `CONFIG.EXTENSION` (`NAME`, `SHORTCUT`, `SHORTCUT_MAC`), filled in `options/options.js`. When you change the extension **name** or **suggested keyboard shortcuts**, update the manifest **`name` / `commands`** and the same fields in **`CONFIG.EXTENSION`** so the options tab title and shortcut help stay accurate.
