## Epic 10 — Notepad UX (Cross-Platform Spec)
**Goal:** Consistent editor behavior specified once, implemented per platform.

### Story 10.2: Click-to-Copy Answer

As a user,
I want to copy a calculated answer to my clipboard by clicking on it,
So that I can quickly paste results into other applications.

**Acceptance Criteria:**

**Given** a line has a computed answer displayed in the answer column
**When** the user single-clicks the answer
**Then** the raw numeric value (without unit) is copied to the system clipboard
**And** a brief flash or checkmark animation provides visual confirmation

**Given** a line has a computed answer with a unit (e.g., `11.023 lbs`)
**When** the user double-clicks the answer
**Then** the full value with unit (e.g., `11.023 lbs`) is copied to the clipboard
**And** a brief flash or checkmark animation provides visual confirmation

**Given** a line has no computed answer (comment, header, or error)
**When** the user clicks in the answer column area for that line
**Then** nothing is copied and no feedback is shown
