Steps

1. 1 None Offstage: provisioning an event to sell (the instance had none on sale) 0:00
2. 2 Guest A stranger opens the home page with no account and no session 0:03 ▣

   The public half is deliberately generous: no cookie wall, no 'sign up to see prices'. Every gate is at the action, never at the page.

3. 3 Guest Tap the event on the upcoming rail 0:04
4. 4 Guest Pick a quantity 0:05
5. 5 Guest Press Buy — still with no account 0:06 ▣
6. 6 Guest Press Pay. This press is the auth trigger and, per plan 42, the last button. 0:08 ▣

   The choice is parked in sessionStorage and the buy URL rides in ?next=, so both halves of the transaction have to survive the hop.

7. 7 Guest Sign in — typing is not a tap, so only the press is counted 0:09 ▣
