Command Center at Scale — Run a 100-Division Tournament Without Drowning

A compact rail with smart presets (Live / Attention / Pinned / All) gives operators focus on tournaments with 50, 80, even 100 divisions. Pin up to 12 to follow live, view up to 4 in a 2×2 grid, share a focus URL with a scorer so they see only their divisions. This update is designed for tournament organizers and players who want a better tournament play experience — less manual work, more control, and a smoother workflow.

What's Included

Compact left rail — one row per division, with state dot + match-counter + live-count + attention badge + pin + view icons

Smart presets — Live / Attention / Pinned / All. Smart fallback: 'Live' auto-promotes to 'All' if nothing is live yet so the rail never lands empty

Pin up to 12 divisions, server-persisted so an operator can pin from desktop and pick up on iPad

Share button copies a focus URL with ?pinned=12,15&preset=pinned. Recipient sees 'Save as my default' pill to persist

View icon adds up to 4 divisions to a side-by-side 2×2 grid (hard-capped, never more); 1-col on narrow viewports

Click any rail row to enter focus mode — only that division shows below, with a smooth scroll + highlight pulse

Aggregate poll updates rail counters every 10s/30s focused/hidden. Deep poll only fires for pinned divisions

Auto-collapses the club-admin sidebar so wide tournaments get maximum horizontal room

First-visit coachmark on 20+ division tournaments (once per user)

AI chat: query_command_center_state + query_command_center_attention tools surface tournament state in natural language

Mobile + tablet parity — phone shows full-screen rail with stack-push detail; tablet shows rail + detail pane side-by-side

Cross-repo parity tripwire spec — backend constants and mobile TypeScript types fail the suite if they drift

Legacy 3-up grid stays as a safety fallback below the rail; flag-flip rollback with zero data migration risk
