Challenge submission for the Unity Junior Programmer pathway: "Debug the App".

Missing particle reference: the CongratScript's particle system field was unassigned (a leftover from a renamed field), which caused a NullReferenceException in Start(). I assigned the SparksEffect particle system to it.

Text never changed: the line that updates the text was inside the wrap-around if, so it only ran when the counter reset. I moved it out so the message switches every cycle.

Invisible sparks: the spark material used the built-in Standard shader, which doesn't render in URP. I switched it to URP Particles/Unlit with additive blending.

Wrong scene in the build: the build included only the empty SampleScene. I replaced it with the actual challenge scene.

I used the unused RotatingSpeed variable to make the text spin. The message swaps exactly when the text is edge-on (90°) to the camera, so it's never shown backwards.

Unity Junior Programmer "Debug the App" challenge. Fixed a missing particle reference (NullReferenceException), a text-switching logic bug, URP-incompatible spark material, and the build scene list.
