What is the difference between a showdown 'ending' and showdown 'closing' in the rules?

Ruling: The terms "ending" and "closing" refer to the same thing - the conclusion of the Showdown. The distinction in wording is inconsistent rather than meaningful.

Nuances:

• The verb "close" is also used to describe turn States (like "Neutral Closed" or "Showdown Closed"), which creates potential confusion
• It would be clearer to use "ends" consistently and reserve "close" only for describing State changes
