- Extract isWithinOperatingWindow() to lib/env.ts (shared) - Park detail page: always fetch Queue-Times, but force all rides closed when outside the ±1h operating window - LiveRidePanel: always show closed ride count badge (not just when some rides are also open); label reads "X rides total" when none are open vs "X closed / down" when some are Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
