2.2.3 No Timing (Level AAA)
What it requires: No essential time limit at all (except for real-time events like an auction, where timing is the point).
Common failure: A flash-sale countdown that actually gates checkout completion (not just marketing pressure) leaves no path to complete the purchase once time expires.
Fix it: Reserve genuinely hard time limits for cases where timing is essential to the transaction (live auctions); for marketing countdowns, don’t let the timer actually block completion of an in-progress action.
