//! `studio.theme.glass-apple` — clean, neutral, frosted-glass
//! Studio theme inspired by Apple's macOS system palette.
//!
//! Cool grays, blue accent, indigo + green + red system
//! colours. Pairs cleanly with FaiEditorStyle.modern (frosted
//! panel + gradient backdrop) for the "Apple sidebar" feel.
//! Light mode reads as a sunlit studio; dark mode reads as
//! a quiet evening workspace.
