# Loading Screen Fix Summary

## Issue
The loading screen was getting stuck at 99% and not transitioning to the main menu.

## Root Cause Analysis
1. **Floating Point Precision**: The loading progress calculation involved adding `0.2 + 0.7 + 0.1`. In standard IEEE 754 double precision, this sum results in `0.9999999999999999`, which is slightly less than `1.0`.
   - The transition condition `loadingProgress >= 1.0` failed because of this.
   - The percentage display showed `99%` because `int(0.999... * 100)` is `99`.

2. **Potential Thread Synchronization**: There was a possibility that the audio loading thread finished loading all tracks but hadn't yet set the `loadingComplete` flag (e.g., due to a delay in thread cleanup/shutdown). This would prevent `musicLoaded` from becoming true, which is also required for the transition.

## Fix Implemented
1. **Precision Handling**: Added a check to force `loadingProgress` to `1.0` if it exceeds `0.99`.
   ```cpp
   if (loadingProgress > 0.99) loadingProgress = 1.0;
   ```

2. **Robust Completion Check**: Modified the condition for `musicLoaded` to accept completion if the number of loaded tracks matches the expected total, even if the thread hasn't officially signaled completion yet.
   ```cpp
   if (Audio::instance().isLoadingComplete() || (totalTracks > 0 && currentTrackLoading >= totalTracks)) {
       Audio::instance().shuffle();
       musicLoaded = true;
   }
   ```

## Verification
- Verified mathematically that the floating point sum was indeed `< 1.0`.
- The code now explicitly handles this case and ensures a smooth transition to the main menu.
