Variable attributes (affect image & variants)
Each combination of variable attribute values becomes a row on the Variation Matrix page, where its image, price and stock are assigned. Tick Has sub-options on a value (e.g. Material = STEEL SERIES) to define its child sub-options beneath it (e.g. colours and body types). Sub-options of the same sub-attribute are alternatives; different sub-attributes under one value are combined, so every parent + sub-option + other-attribute combination gets its own matrix row.
