Signet

The shared design system for CVER's native macOS apps — snapsift, clioil, reepub, andross, and the rest. One source of truth for the palette, design tokens, glass surfaces, components, and the borderless "liquid glass" window chrome, so every app renders as the same family.

The name is the metaphor: a signet stamps CVER's identity onto each app. The aesthetic will follow the times (today's liquid glass won't be forever), but the seal — the family identity — stays. That's also why the public API keeps a brand-stable CVER* prefix (CVERTheme, CVERRadius, .cverTheme) while the package is named Signet: if this package is ever renamed in a future design era, app code changes one import line, not every call site.

This came out of a real observation: every CVER app had independently grown the same color role taxonomy — ground / deep / accent / highlight / text / border plus positive / warning / danger — and just drifted on the hex values and the plumbing. Signet collapses that drift into one package.

What's inside

Area	API	Notes
Color hex	Color(hex: 0x0a8c8e), Color(hex: "#0a8c8e")	one canonical init (replaces three drifted copies)
Theme	CVERTheme protocol, ReefTheme (default), AndrossTheme	inject via .cverTheme(_:), read via @Environment(\.cverTheme)
Palette	Color.reef*, Color.androidGreen / .slate*	static constants for drop-in migration
Tokens	CVERRadius, CVERSpacing	a real ladder, not magic numbers
Typography	.cverWordmark()	lowercase + monospaced + bold house wordmark
Surfaces	.liquidGlassCard(), .cverPanel()	frosted glass for chrome; opaque for content
Components	.buttonStyle(.cver()), .cverBanner(_:), CVERGate	the repeated UI, factored out
Window	.glassWindowChrome()	borderless rounded frosted window (opt-in)

Adding it

// Package.swift
dependencies: [
    .package(url: "https://github.com/CVERInc/signet", branch: "main"),
],
targets: [
    .executableTarget(name: "MyApp", dependencies: [
        .product(name: "Signet", package: "signet"),
    ]),
]

import Signet

@main struct MyApp: App {
    var body: some Scene {
        WindowGroup { ContentView().cverTheme(ReefTheme()) }
    }
}

CVER apps pin in-house deps to branch: "main" / latest — see the family convention — so improvements land everywhere on the next build.

The one rule worth repeating

.liquidGlassCard() is for chrome — sidebars, toolbars, cards, overlays. Do not put glass behind a canvas where color accuracy matters (e.g. snapsift's photo grid): glass lets the desktop bleed through and shifts perceived color. Glass chrome, opaque content.

Building

swift build · swift run SignetTests (framework-free smoke runner). Pinned to swift-tools 5.9 / macOS 13 so every CVER app can depend on it.
