Current topic: "Exploring Affected Files"
Topic summary: I have read the issue description and identified the key components that need to be created, modified, or removed. I am now exploring the codebase to locate these files and understand their current implementation. This includes `ReadOnlyWarningBanner`, `PaywallScaffold`, various screens, and their corresponding viewmodels. I will also examine `AppGate.kt` as it is the source of truth for the logical states.

Strategic Intent: Exploring the codebase to locate affected files and understand current implementation.
