See which SKUs collide after cleanup.
Paste two to fifty SKU strings, one per line. This snapshot applies one explicit case, separator, and length rule to the whole batch, then shows which distinct inputs collapse to the same normalized value. Submitted SKUs are not stored; only aggregate page-view and run counts are retained.
