# MacWindowFrame

> Decorative macOS-style window chrome that wraps showcase content such as code demos, screenshots, and portfolio pieces.

- Status: beta
- Group: structure
- Page: https://www.digitaltableteur.com/design-system/components/mac-window-frame
- Contract: https://www.digitaltableteur.com/contracts/v1/MacWindowFrame.contract.json

## When to use

MacWindowFrame wraps showcase content; code demos, screenshots, portfolio pieces; in decorative macOS-style chrome. The title and optional action button come through i18n keys (`titleKey`, `actionLabelKey`). It is presentation, not a real window: the traffic lights are paint, and anything needing dialog semantics (focus trap, dismissal) belongs in Modal.

## When not to use

- Do not use it as an actual window or dialog; Modal owns focus and dismissal semantics.

## Look-alikes

- Modal: Do not use it as an actual window or dialog; Modal owns focus and dismissal semantics.

## Rules

Every item under When not to use is a MUST NOT. MUST and SHOULD follow RFC 2119.

| Level | Rule | How it is checked |
| --- | --- | --- |
| MUST | Required stories produce no axe violations at the configured severity. | Automated by `npm run test:stories:matrix:ci`. WCAG 2.5.8. |
| MUST | The accessibility tree (role, name, state) matches the committed snapshot for every required story. | Automated by `npm run test:stories:matrix:ci`. WCAG 1.3.1, 4.1.2. |
| MUST | The component remains legible and operable under a real browser forced-colors: active pass. | Automated by `npm run test:stories:hc`. |
| MUST | A human completed an end-to-end accessibility review of this component. | Manual review, last on 2026-05-28. |
| SHOULD | Use it to frame demos and screenshots where the desktop-app look sells the context. | Not stated in the contract. |

| SHOULD | Use density="compact" inside dense grids of demos. | Not stated in the contract. |
| SHOULD | Provide onAction only when the button does something real; the button hides itself otherwise. | Not stated in the contract. |
| SHOULD NOT | Do not rely on the traffic-light dots for any function; they are decoration and convey nothing to AT. | Not stated in the contract. |
