Code Review

This pull request introduces a new ViewSwitch component to toggle between grid and table view modes. The review feedback highlights a UX bug where the tooltips are inverted relative to the active view mode, an accessibility anti-pattern where the tooltip wraps the inner icon instead of the interactive IconButton, and hardcoded UI strings that should be exposed as props to support internationalization.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
