not sure if the above userscript caused a memory leak with certan thread pages with different iframe configurations but just in case I refactored for memory improvements using deepseek non-reasoning.
Here's the complete updated userscript with memory optimizations:

## Key Changes Made:
1. **Optimized Selector**: Changed from complex 134-ID selector to simple `iframe[data-s9e-mediaembed]` with manual filtering
2. **Throttled Observer**: Added proper timeout management to prevent excessive scans
3. **Observer Cleanup**: Added disconnect logic for page navigation/unload
4. **Reduced Observer Scope**: Removed unnecessary attribute/characterData observation
5. **Memory Management**: Proper cleanup of timeouts and observers
## Verification Checklist:
1.

All media embeds still get reload buttons
2.

Per-site styling and positioning preserved
3.

Reload functionality works on click only
4.

Dynamic content detection still works
5.

Memory usage should be significantly reduced
6.

No breaking changes to existing functionality
The script maintains all original features while reducing memory consumption through optimized DOM queries and proper resource cleanup.
