**Location:** `frontend/src/components/shot/ShotDetailPanel.vue`

### 2. ShotBrowser.vue (UPDATED)
Enhanced the existing shot browser to integrate the detail panel.

**New Features:**

- Responsive behavior (panel on desktop, sheet on mobile)

**Location:** `frontend/src/components/shot/ShotBrowser.vue`

### 3. ShotCard.vue (UPDATED)
Updated the shot card to use the detail panel instead of separate task view.

**Changes:**
- Changed "View Tasks" to "View Details"
- Emits select event to show detail panel

**Location:** `frontend/src/components/shot/ShotCard.vue`
