You're an amateur home bartender who keeps buying duplicate bottles and forgetting what's already on the shelf. Build a single-page **cocktail ingredient tracker** that lets you manage your home bar inventory.

Users should be able to:
- **Add a spirit or ingredient** with a name, category (e.g. Whiskey, Liqueur, Bitters, Mixer, Garnish), and an optional tasting note or brand detail.
- **Mark items as In Stock / Running Low / Out**, shown with a clear visual indicator (color badge or icon).
- **Filter the cabinet** by category so you can quickly see what you have in each section.
- **Delete items** they no longer own.

All data must persist in `localStorage` so the cabinet survives a page refresh. The UI should feel like a stylish bar shelf — think dark background, warm amber accents, clean card layout. No backend, no login required.
