Storefront gains a Filters drawer holding the category tree, colour-coded tag pills, and a price range, with applied filters shown as removable chips. Filter state lives in the URL query string, so a filtered view is shareable and the back button works. Item cards now show their category and tags. Admin gains Categories and Tags tabs, and the item form gains a category TreeSelect plus a tags Select that creates new tags on the fly. The admin category tree tracks expansion in state rather than using defaultExpandAll: that prop is evaluated once at mount, so a branch added afterwards rendered collapsed and its children were unreachable. Creating or moving a node now expands its parent. Caught by the new admin e2e spec. The chip row is marked as a named group so its "Clear all" stays distinguishable from the drawer's.
