Hand and stack zones had near-identical addCardImpl() implementations, differing only in whether resetState() preserves annotations.
Extract the shared pattern into a template function (CardZoneAlgorithms::addCardToList) to eliminate duplication and enable isolated testing without Qt dependencies.
Pile, table, and zone-view logic are intentionally excluded — their post-add behavior (signals, coordinate placement, hidden cards) is materially different.
