/**
 * Verification script for replay viewer with real match replay
 * Tests that the replay viewer loads and plays a real (non-demo) match replay.
 *
 * Tests:
 * 1. Pick a completed match ID from the DB (m_tprjf4ij in real-replay.json)
 * 2. Attempt to load its replay via /data/real-replay.json
 * 3. Verify canvas renders the grid, bots, energy cells
 * 4. Verify playback controls work (play/pause, step, speed)
 * 5. Verify transcript panel generates turn-by-turn events
 * 6. Verify win probability sparkline renders (may be empty if no commentary data)
