+## Epic 7 — macOS App (Swift/SwiftUI)
+**Goal:** A beautiful, native macOS app that feels like it belongs on the platform.
+
+### Story 7.8: Spotlight & Quick Look
+
+As a **macOS user**,
+I want CalcPad sheets to be indexed by Spotlight and previewable via Quick Look,
+So that I can find and preview my calculations from Finder and Spotlight search without opening the app.
+
+**Acceptance Criteria:**
+
+**Given** a sheet named "Tax Calculations 2026" is saved
+**When** the user searches "Tax Calculations" in Spotlight
+**Then** the CalcPad sheet appears in the search results
+**And** selecting it opens the sheet in CalcPad
+
+**Given** CalcPad sheets are saved as files
+**When** the app indexes them using `CSSearchableItem`
+**Then** the index includes the sheet title, content keywords, and last-modified date
+
+**Given** the user selects a `.calcpad` file in Finder and presses Space
+**When** Quick Look is triggered
+**Then** a formatted preview of the sheet is displayed showing the two-column layout (expressions and results)
+
+**Given** a sheet is deleted in CalcPad
+**When** the deletion is processed
+**Then** the corresponding Spotlight index entry is removed
