+
+### Added
+- Added separate `Research` and `Results` workspaces so new runs and saved run browsing live in distinct flows while preserving bundled map selection.
+- Added dedicated Basic and Deep Research results views, plus a public landing page and dedicated auth route for the unauthenticated experience.
+
+### Changed
+- Made Basic research map-first by requiring a dropped pin or current location, sending coordinate-based searches through the API, and cleaning up shared map presentation.
+- Simplified shared Google Maps rendering by moving Basic, Deep Research, and result review maps onto the same cleaner visual style.
+
+### Fixed
+- Fixed local logout behavior so the session cookie is cleared consistently and optional session-id logout requests can remove the active server session record.
