Components
Button
A D-pad-focusable action. Renders a real <button> with the focusable class, so useDpad walks it and activates it on Enter/Space. Edge + focus ring are emitted light, never fills.
Installation
npx @glasskit-ui/cli add buttonInstall the SDK (it provides GlassViewport, useDpad and the stylesheet), then copy these files into your project:
npm install @glasskit-ui/react// components/lib/utils.tsexport type ClassValue = string | number | null | undefined | false;/** * Join truthy class names. Dependency-free on purpose: the lens components * style via bespoke semantic classes (no conflicting Tailwind utilities to * de-dupe), so this needs no clsx/tailwind-merge and resolves from anywhere * the registry is vendored. */export function cn(...inputs: ClassValue[]): string { return inputs.filter(Boolean).join(" ");}/** * Accessible name from a free-form `label` prop: the label itself when it's a * plain string, otherwise undefined (a ReactNode can't become an aria-label). */export function stringLabel(label: unknown): string | undefined { return typeof label === "string" ? label : undefined;}// components/glasskit/button.tsximport type { ReactNode } from "react";import { cn } from "../lib/utils";/** * <Button> — a D-pad-focusable action.

Toaster
The toast / notification SYSTEM — Sonner (Emil Kowalski's library) themed to the lens. Mount <Toaster> once, then fire imperatively with toast(); it handles the queue, stacking, auto-dismiss, and enter/exit motion. Top-anchored — Screen's Cue line owns the bottom strip.
Confirm
A decision screen: a prompt plus a two-button action bar. Drop it into a Screen stage; useDpad seeds focus on the primary action.
