+# CUB-196: CameraCard Component Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** Build the CameraCard React component that displays one camera's live status with color-coded battery, pulsing recording indicator, and online/offline state.
+
+**Architecture:** Single component at `src/components/CameraCard.tsx` consuming `CameraStatus` from the existing Zustand store. Uses Tailwind for styling (existing dark dashboard palette), lucide-react for icons. No new dependencies needed — everything is already in `package.json`.
+
+**Tech Stack:** React 19, TypeScript 5.7, Tailwind CSS 3.4, Zustand 5, lucide-react 0.469
+
+---
+
+## Prerequisites
+
+Before any task, ensure the repo is on `dev` and clean:
+
+```bash
+cd /mnt/ai-storage/projects/remote-rig
+git checkout dev
+git pull origin dev
+git checkout -b agent/<your-agent-name>/CUB-196-cameracard
+```
+
+---
+
+### Task 1: Create the CameraCard component
+
+**Objective:** Build `src/components/CameraCard.tsx` with all required display elements.
+
+**Files:**
+- Create: `src/components/CameraCard.tsx`
+
+**Step 1: Create the component file**
+
+Create `src/components/CameraCard.tsx`:
+
+```tsx

+/** Format ISO timestamp as relative time (e.g. "2m ago", "1h ago") */
+function formatRelativeTime(iso: string): string {
+  const diff = Date.now() - new Date(iso).getTime()
+  const sec = Math.floor(diff / 1000)
+  if (sec < 60) return 'just now'
+  const min = Math.floor(sec / 60)
+  if (min < 60) return `${min}m ago`
+  const hours = Math.floor(min / 60)
+  if (hours < 24) return `${hours}h ago`
+  const days = Math.floor(hours / 24)

+```
+
+**Step 2: Add test config**
+
+Add to `vite.config.ts` the `test` block (reference: https://vitest.dev/config/):
+
+```ts
+/// <reference types="vitest/config" />
+// ... existing imports and config, add:
+test: {
+  globals: true,
+  environment: 'jsdom',
+  setupFiles: [],
+}
+```
+
+**Step 3: Create setup file**
+
+Create `src/test-setup.ts`:
+
+```ts
+import '@testing-library/jest-dom'
+```
+
+Update vite.config.ts `setupFiles` to `['./src/test-setup.ts']`.
+
+**Step 4: Add test script**
+
+Update `package.json` scripts:
+
+```json
+"test": "vitest run",
+"test:watch": "vitest"
+```
+
+**Step 5: Write CameraCard tests**
+
+Create `src/components/CameraCard.test.tsx`:
+
+```tsx

+
+**Step 6: Run tests**
+
+```bash
+npm test
+```
+
+Expected: All 15 tests pass.
+
+**Step 7: Commit**
+
+```bash
+git add src/components/CameraCard.test.tsx src/test-setup.ts vite.config.ts package.json
+git commit -m "CUB-196: add CameraCard unit tests (vitest + testing-library)"
+```
+
+---
+
+## Verification
+
+After all tasks complete:
+
+```bash
+# Type-check
+npx tsc --noEmit
+
+# Build
+npm run build
+
+# Tests
+npm test
+```
+
+All must pass before pushing.
