Bare BaseTask call fired from DeckDecisionUI.cs:140 (Arena "View Deck"
path) and the TK2 prep screen. Client task has no Parse() override —
just checks result_code, ignores body. Prod (4 captured instances
across traffic_prod_taketwo_selections + traffic_prod_tradeables_capture)
unanimously responds with data: [].
Routing smoke added.
