+### Changed
+- Web UI: Test Hand uses a default fanned layout on desktop with tightened arc and 40% overlap; outer cards sit lower for a full-arc look
+- Desktop Test Hand card size set to 280×392; responsive sizes refined at common breakpoints
+- Theme controls moved from the top banner to the bottom of the left sidebar; sidebar made a flex column with the theme block anchored at the bottom
+- Mobile banner simplified to show only Menu, title; spacing and gaps tuned to prevent overflow and wrapping
+
+### Fixed
+- Prevented mobile banner overflow by hiding non-essential items and relocating theme controls
+- Ensured desktop sizing wins over previous inline styles by using global CSS overrides; cards no longer shrink due to flex
