                  Preview of the stratified block randomisation for the current 
                  strata variables, block size and seed. This updates live, 
                  before you generate the plate layout — check that each strata 
                  level is spread evenly across the blocks, and adjust the block 
                  size or seed if it looks unbalanced.
