- This page enumerates ONLY this origin's own storage: localStorage, sessionStorage, IndexedDB database names, and Cache Storage keys for nutter.tools. Other sites' data is not reachable from here and never shown.
- The inspector is read-only by design: names, counts, and sizes. No delete, no clear, no value editor; destructive controls are out of scope for this tool.
- Key NAMES are listed; VALUES are not rendered (a stored value can be anything, including something you would rather not paste on screen). Sizes are UTF-8 byte sums.
- The quota estimate is the browser's own StorageManager.estimate(): an approximation the engine recomputes on demand; the number moves as the browser's eviction policy does.
