Refactor a SKU regex into named parts
Use named groups and noncapturing structure to extract SKU components safely.
Refactor a SKU regex so changes to structural groups do not corrupt downstream inventory fields. Named data groups, noncapturing structure, explicit optional segments Numbered captures look harmless until a new optional group changes every position that downstream code reads.
