Build a single-page savings goal tracker that lets users manage multiple visual "jars" — each representing a personal savings goal (e.g., vacation fund, new laptop, emergency cushion).

Each jar has:
- A **name** and optional emoji icon
- A **target amount** (e.g., $500)
- A running **saved amount**, updated by logging deposits (with an optional note and date)
- A **visual fill meter** showing progress as a colored liquid rising inside a jar shape
- A **status badge**: Not Started / In Progress / Reached 🎉

Users can:
- Add new jars
- Log a deposit to any jar (amount + optional note)
- View a mini deposit history per jar (last 5 entries)
- Delete a jar they no longer need

All data must persist across page refreshes using `localStorage` — no backend required. The UI should feel friendly and motivating: warm colors, smooth progress fills, and a celebratory state when a jar hits 100%.
