You're helping someone plan decorations for a birthday party. Build a single-page widget that calculates how many balloons are needed for a party setup.

The user enters:
- **Number of guests** (numeric input)
- **Number of balloon arches** (each arch needs 12 balloons)
- **Number of table centerpieces** (each centerpiece uses 5 balloons)
- **Ceiling cluster count** (each cluster uses 7 balloons)

The widget instantly shows:
- **Total balloons needed** (live-calculated sum)
- **Estimated bags to buy** (balloons typically sold in bags of 25; always round up)
- **A fun color-coded breakdown** showing each decoration type's balloon count as a labeled row

Also include a **Reset** button that clears all inputs back to zero. All calculations update in real time as the user types — no submit button needed. Keep the UI cheerful and party-themed with bright colors.
