    let author: String
    let background: ThemeColor
    let foreground: ThemeColor
    let cursor: ThemeColor
    let selection: ThemeColor
    let ansi: ANSIColors  // All 16 ANSI colors
}

ThemeColor

Supports hex initialization and conversion to NSColor/SIMD4:

let color = ThemeColor(hex: "#A78BFA")
let nsColor = color.nsColor      // For AppKit
let simd = color.simd4           // For Metal shaders

Custom Themes

let engine = ThemeEngine()
engine.addCustomTheme(myTheme)
try engine.loadTheme(named: "my-custom-theme")

Hot Reload

Theme changes are reflected immediately through @Observable:

engine.onThemeChange = { newTheme in
    // Re-render terminal with new colors
}
