Tuck is a lightweight read later extension that saves article content locally for offline reading and reader mode functionality.

The extension uses:
- activeTab to access the current page only when the user interacts with the extension
- scripting to extract readable article content
- storage and unlimitedStorage for locally saved articles and user preferences
- contextMenus for quick-save actions

No user accounts, advertising trackers, or remote code execution are used.

All saved content is stored locally on the user’s device.
