Command Hall (/admin, owners only) has a new layout: a side rail grouped into Watch, Analyse, Players and Control; a Dashboard with live room and player gauges, runs per day, win rate by class, difficulty and zone, version adoption and 24-hour performance; charts on Runs, Feedback, Performance and the new Versions view; room cards with health bars; tuning fields with a distance-from-default bar, per-field reset and a change list before saving; batch feedback triage (up to 20, one password, each change audited); sortable, searchable lists; links that keep filters and open records; auto-refresh and keyboard shortcuts (press ?). Players see no change.
