/**
 * Profile modal, blocked list, sync states, and moderation control tests.

 * Scenarios covered:
 * - SCN-profile-open: Profile modal opens when logged in
 * - SCN-profile-gated: Profile button hidden when logged out
 * - SCN-profile-sync-status: Sync status elements are rendered
 * - SCN-profile-blocked-empty: Empty blocked list shows appropriate state
 * - SCN-profile-permission-prompt: Permission prompt CTA is rendered
 * - SCN-decrypt-passthrough: Default decrypt behavior passes through
 * - SCN-decrypt-timeout: Timeout decrypt behavior triggers timeout path
 * - SCN-decrypt-error: Error decrypt behavior triggers error path
 * - SCN-list-sync-events: List sync event capture tracks auth state changes
