## Epic 7 — macOS App (Swift/SwiftUI)
**Goal:** A beautiful, native macOS app that feels like it belongs on the platform.

### Story 7.10: Widgets (Notification Center)

As a **macOS user**,
I want CalcPad widgets in Notification Center and the Lock Screen,
So that I can glance at pinned calculation results without opening the app.

**Acceptance Criteria:**

**Given** the user adds a CalcPad small widget to Notification Center
**When** the widget is configured with a pinned calculation
**Then** the widget displays the current result of that calculation

**Given** the user adds a CalcPad medium widget to Notification Center
**When** the widget is configured with a pinned sheet
**Then** the widget displays the last 5 lines of that sheet with their results

**Given** a pinned calculation's inputs change (e.g., a variable in the sheet is updated)
**When** the widget timeline refreshes
**Then** the widget shows the updated result

**Given** the user adds a CalcPad Lock Screen widget
**When** the Lock Screen is displayed
**Then** the widget shows the pinned calculation result in a compact format

**Given** the user taps/clicks on the widget
**When** the system processes the interaction
**Then** CalcPad opens and navigates to the relevant sheet
