Condition Analysis

Quick match-day weather and venue filters up top, with deeper surface and pace profiling below.

Historical player-page weather uses one stored venue-date weather value per match day. Temperature, humidity, wind, and condition labels all follow that same day-level model, not match-time or hourly weather.
