Organizing products: languages, labels, search, ordering

• Language sections — inventory groups into collapsible per-language sections with count/units/cost subtotals.
• Labels — free-form tags (Pokemon, One Piece, Sealed…) set on any product. Click a chip or use the search bar to filter; the Overview charts capital by label.
• Search — the bar filters by name, label, and language at once; multiple terms combine ("pokemon japanese booster").
• Manual order — "Reorder products…" enters a drag-and-drop mode (e.g. arrange Japanese sets by release date), saved explicitly. Column-header sorting overlays it; "back to manual order" resets.
