+## 2026-01-21 - US-010
+- What was implemented: Password reset - set new password page
+- Files changed:
+  - src/app/reset-password/page.tsx - new file with password reset form
+  - src/app/login/page.tsx - updated to show success message from password reset
+- **Learnings for future iterations:**
+  - Supabase recovery tokens come via URL hash fragment with type=recovery
+  - Use setSession() with access_token and refresh_token from hash to establish recovery session
+  - Show loading state while verifying token validity (tokenValid === null)
+  - Show error state with link to request new reset if token is invalid
+  - After password update, sign out the user and redirect to login with success message
+  - Use query param (message=password_reset_success) to pass success state between pages
+  - Login page uses useSearchParams to read and display success messages
+  - Success messages styled with green background (bg-green-50)
