The calculation for
muwhendynamic_shift_lenis provided can be simplified. Sincebase_shiftandmax_shiftare bothmath.log(3), the call to_calculate_shift_qwen_imagewill always returnmath.log(3). You can directly assign this value tomuand remove the now-unusedbase_shiftandmax_shiftvariables for better readability and maintainability.
