Prediction hero now shows ranked TOP PICK and 2ND PICK with EV per unit
bet (P(win)*2.9 - 1). Bet Size Advisor panel shows Kelly criterion
fraction (capped 25%), best chair with confidence, and historical bet
rank insight (how often lowest/highest-bet chair wins).
Live Market Sentiment section tracks whale trend (top 5 bettors by amount)
and public trend (total pool distribution) in real-time via WebSocket,
mirroring the live dashboard. Notes highlight agreement/divergence between
model pick and crowd favorite.
Historical crowd analysis cards show how often the most-bet, mid-bet, and
least-bet chairs actually won across all games.
Round result flash now includes whale/public pick accuracy alongside the
model prediction result. user_bet WebSocket events are tracked to build
per-round bettor profiles for whale analysis.
