💡Insights & Learnings

Learning: OAuth can show brief error messages even on successful auth due to timing between session validation and redirect. Need to handle this UX gracefully.

Decision: Implemented full cloud sync now (not just notes) to ensure users don't lose designs and boards - these represent significant user investment.

Learning: AuthSessionMissingError can occur during sign-out if the session is already invalidated. Handle gracefully instead of showing error.

Decision: Created comprehensive manual test scenarios before launch to ensure systematic QA coverage across all features.
