Update Orion's entire UI (toolbar, tabs, sidebar, menus, etc.) to match macOS 26's "Liquid Glass" design language when using macOS 26. This is purely a visual refresh for contemporary aesthetics and OS consistency. There are no workflow changes in that everything works the same but looks and feels native to macOS 26.
This is simply a UI refresh, so a user will use the browser like they normally use, just under the new design language. For an example of a refresh you can see Safari or Safari TP on macOS/iOS/ipadOS/visionOS 26. This feature would make Orion look more native to the OS on macOS 26.
I haven't been able to test if iOS/iPadOS/visionOS's Orion has the updated liquid glass design language, I suspect not but that's speculation.
