Liquid Glass Forms (macOS 26+)

Two-Layer Architecture

• Glass layer: toolbars, sidebars, inspector shells, section containers (structural)
• Content layer: form rows and fields (solid/neutral)

Glass is for the navigation/control layer floating above content, not a blanket background for every input.

Glass Modifier Usage

On macOS 26, there is ONE glass modifier: glassEffect(_:in:).

• Section containers: Apply as a .background {} on a RoundedRectangle
• Special tiles/callouts: Apply in a ZStack on a shape (rare)

⚠️ glassBackgroundEffect(displayMode:) is visionOS-only — it does NOT compile on macOS.
