// Wave 4A — OUTLOOK MODE (never-empty slate grid, Step 3).
// The game grid must NEVER dead-end in a "NO SLATE" CTA. When there are no
// live games it falls back to REAL always-available data: yesterday's PROVEN
// A-tier receipts + tomorrow's date-pinned schedule preview. A network
// fetchError stays an ERROR state (a fetch failure is never a fake outlook).
