| 3 | Fill Values | 6s | Values populate one by one: 10, 25, 8, 47, 3, 16 |
| 4 | Index Access | 7s | arr[2] highlighted; index vs value distinction shown |
| 5 | Iteration | 8s | Orange pointer sweeps left to right, highlighting each element |
| 6 | Append | 5s | New box 6 appears on right with value 99 |
