- When a WD4 is played, the victim can challenge or accept
- Challenge succeeds if the WD4 player had a card matching the
previous color — they draw 4 instead
- Challenge fails: victim draws 6 (4 + 2 penalty)
- Bot as victim: challenges probabilistically based on opponent
hand size (10-70% chance, more cards = more likely to challenge)
- Bot as player: 20% chance to illegally play WD4 when it has
matching color cards, making challenges meaningful against it
- Auto-play defaults to accepting (safe option)
- Challenge phase integrates with existing turn timer

Blackjack:
- Fix handValue soft flag for multi-ace hands (A+A+5 returned soft=false,
causing dealer to incorrectly stand on soft 17)
- Fix loss display showing €-50 instead of -€50
- Round down Blackjack 1.5x payout per requirements (math.Floor)
- Restrict !bjboard to games room like all other game commands
- Fix leaderboard showing misleading W/L (pushes counted as losses)
- Notify user when bet is capped to max instead of silently capping
- Fix bet max message to use min(MaxBet, maxAvailable)
- Rework to simultaneous play: all players hit/stand independently
with one shared round timer, reminders at 30s and 10s remaining
- Add !blackjack deal to skip the 60s join wait
- Add mid-round forfeit via !blackjack leave during play
- Set minimum 5s delay for reminder timers to avoid spam on low timeouts
Multiplayer UNO:
- Fix lobby race conditions: move euro debit inside mutex lock to
prevent lobby overwrites and missed refunds
- Extract shared applyCardEffects to deduplicate card effect logic
from applyAndAnnounce, botMultiTurn, and applyAutoEffects
- Add 10-minute game inactivity timeout with refunds (was in
requirements but not implemented)
- Add card count to all "draws a card, turn passes" room messages
so spectators can track hand sizes
