+## 2026-01-21 - US-008
+- What was implemented: Logout functionality component
+- Files changed:
+  - src/components/LogoutButton.tsx - new client component with signOut and redirect
+  - src/components/.gitkeep - removed (no longer needed)
+- **Learnings for future iterations:**
+  - LogoutButton is a reusable component that will be used in the navbar (US-011)
+  - Component uses 'use client' directive for client-side auth operations
+  - Loading state prevents double-clicks during signOut
+  - Styled with neutral zinc colors to work as a secondary button in navbars

+- What was implemented: Password reset - forgot password page
+- Files changed:
+  - src/app/forgot-password/page.tsx - new file with forgot password form and email reset
+- **Learnings for future iterations:**
+  - resetPasswordForEmail requires redirectTo option to specify where user lands after clicking reset link
+  - Use `window.location.origin` to get the current site URL for redirectTo
+  - Page shows different UI after success (conditional rendering with success state)
+  - Use ' for apostrophe in JSX to avoid HTML entity issues
+  - Follow same styling pattern as login page for consistency across auth pages
