Snapshot-Based Approach +- **Decision**: Store complete state snapshots rather than incremental changes +- **Rationale**: Simpler implementation, easier to maintain, sufficient performance for 100 entries +- **Trade-off**: Higher memory usage, but negligible for mesh data size + +### 2. Drag Operation Optimization +- **Decision**: Save state once at drag start, not on every movement +- **Rationale**: Prevents creating dozens/hundreds of undo entries per drag +- **Implementation**: `prepareForDrag()` called on drag start, `updateMeshPoint()` with `saveForUndo=false` during drag + +### 3.
