// Player feedback after 0.1.0, #4 (workstream WA): the 突变细胞 item card says what the official text leaves out — the
// cell is not consumed, it returns to the hand with the destroyed operator's other equipment, and the new operator joins
// the 整备区 to be deployed again (official footage; PR #2) (items.json `note`, built by tools/build-data.mjs ITEM_RULES;
// server: builtinMeta char_chess_transformation_equip).
