- Make each transition boundary symmetric (left_overlap controls MAIN→TRANS,
right_overlap controls TRANS→MAIN) so frame indices map 1:1 with no repeats
- Track committed frames per folder to cap overlaps and prevent over-allocation
- Fix float truncation in frame mapping (int→round) that caused off-by-one dupes
- Sync trim slider to follow frame selection in Sequence Order / With Transitions
- Defer expensive file list rebuild to mouse release for smooth trim slider drag
- Apply trim settings to transition folders in both display and export paths
- Refresh trim slider after session restore to show correct file counts
