storytelling¶

payment checkout¶

Checkout, told twice. The first scenario is the path everyone draws; the second is the one that actually costs money, and it is the reason status exists as a first-class attribute rather than a colour convention.

cut over to v1.5¶

A blue/green deployment: how traffic moves to a new version with no gap.

authorization code flow¶

OAuth 2.0 authorization code flow, told as an explorable explanation.

sign in with an external IdP¶

An OIDC login through authapiservice, as the shared engine actually runs it.
