- Replace turn.kept running sum with priorKept + selectionScore model so the
banked total always reflects all set-aside dice in the current cycle, enabling
higher N-of-a-kind bonuses when extending sets.
- Update bestScoring and hasScoring to consider setAsideDice; use brute-force
subset search (feasible for ≤6 dice) instead of greedy strategy for correctness.
- Add breakdownScoring helper to decompose a combined dice set into labeled groups.
- Add updateExplainPanel showing "Prior rolls", scoring groups, and total with
"(need 500)" note when off-board requirement isn't met; format scores >999 as K,DDD.
- Refactor selectionScore/selectionValid to score the combined set (setAsideDice + selection).
- Use bestScoring(rolled, setAsideDice) in onScoreAll and AI for optimal picks.
- Fix scratch paper preview to use priorKept + selectionScore consistently.
- Add hot dice handling: carry cycle score into priorKept and reset setAsideDice.
- Slots: guard card artwork loading to avoid errors when texture is missing; adjust bulb positions accordingly.
