Old links still work after you rename a show.

You're running a show and you want to rename it from 'Laser Coin 001' to 'Challenge Coin'. You change the name. But anyone who shared the old link still lands on the right page because the system keeps the old link working.

This matters because shares are forever. A customer might have bookmarked the old link or shared it on social media months ago. If the link breaks, they hit a dead end. Now they don't.

The system keeps track of the old names so you can rename things without breaking links that are already out there.
