Feature request: distinct visual theme for the Code tab vs claude.ai

Summary

The Claude desktop app's Code tab (Cowork) and the regular claude.ai chat interface look nearly identical. It would help to have a way to visually distinguish them at a glance — for example a different background color, accent color, or theme applied specifically to the Code tab.

Motivation

When switching between the Code tab and a claude.ai chat tab/window, the near-identical layout makes it easy to lose track of which interface is currently in view. A distinct color scheme (or other visual marker) for the Code tab would make this immediately obvious without reading window titles or tab labels.

Suggestion

• Allow a custom accent/background color for the Code tab, configurable in Settings.
• Alternatively, apply a subtle default visual difference (e.g. a colored title bar or sidebar) so Code sessions are distinguishable from claude.ai at a glance.
