+# Mobile Stat Cards Responsive Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Implement two-column flexbox layout for stat cards across Inventory, Logs, and Admin pages to fix content overflow on mobile iPhone screens.
+
+**Architecture:** Create a reusable `StatCard` component with responsive Tailwind classes (`flex justify-between`, responsive font sizing, label truncation). Replace inline stat displays on three pages with this component.
+
+**Tech Stack:** React, Next.js 15, Tailwind CSS, Lucide Icons
+
+---
+
+## File Structure
+
+**Files to Create:**
+- `frontend/components/StatCard.tsx` — Reusable stat card component
+
+**Files to Modify:**
+- `frontend/app/inventory/page.tsx` — Replace stat displays with StatCard component
+- `frontend/app/logs/page.tsx` — Replace stat displays with StatCard component
+- `frontend/app/admin/page.tsx` — Replace stat displays with StatCard component
+
+---
+
+## Task 1: Create Reusable StatCard Component
+
+**Files:**
+- Create: `frontend/components/StatCard.tsx`
+
+- [ ] **Step 1: Create the StatCard component file**
+
+Create `frontend/components/StatCard.tsx`:
+
+```tsx
+import React from 'react';
+import { LucideIcon } from 'lucide-react';
+
+interface StatCardProps {
+  label: string;
+  value: number;
+  icon?: LucideIcon;
+}
+
+export default function StatCard({ label, value, icon: Icon }: StatCardProps) {
+  return (
+    <div className="flex justify-between items-center gap-2 p-4 bg-slate-900 rounded-lg">
+      {/* Icon + Label Container */}
+      <div className="flex items-center gap-2 min-w-0">
+        {Icon && <Icon className="w-5 h-5 text-primary flex-shrink-0" />}
+        <span className="text-sm md:text-base text-slate-400 truncate">
+          {label}
+        </span>
+      </div>
+
+      {/* Number (Right) */}
+      <span className="text-lg md:text-xl font-black text-white whitespace-nowrap">
+        {value}
+      </span>
+    </div>
+  );
+}
+```
+
+**Key Implementation Details:**
+- `flex justify-between items-center` — Label left, number right, vertically centered
+- `gap-2` — 8px spacing between label and number
+- `p-4` — 16px padding on mobile
+- `bg-slate-900 rounded-lg` — Dark background, rounded corners
+- `min-w-0` — Allows label container to shrink (enables truncate)
+- `text-sm md:text-base` — Label: 14px mobile, 16px desktop+
+- `truncate` — Label ellipsis if too long
+- `text-lg md:text-xl` — Number: 18px mobile, 20px desktop+
+- `whitespace-nowrap` — Number never wraps
+- `flex-shrink-0` on icon — Icon doesn't shrink
+
+- [ ] **Step 2: Commit the component**
+
+```bash
+git add frontend/components/StatCard.tsx
+git commit -m "feat: create reusable StatCard component with responsive layout
+
+- Two-column flexbox layout (label left, number right)
+- Responsive font sizing (sm/md breakpoints)
+- Label truncation for overflow handling
+- Optional icon support via Lucide
+- Ready for use across Inventory, Logs, Admin pages"
+```
+
+---
+
+## Task 2: Update Inventory Page Stat Cards
+
+**Files:**
+- Modify: `frontend/app/inventory/page.tsx`
+
+- [ ] **Step 1: Read the current inventory page to find stat card implementations**
+
+Look for sections displaying:
+- "Categories" with count
+- "Item Types" with count
+- "Total Boxes" with count
+
+Expected current pattern (inline flex layout):
+```tsx
+<div className="flex items-center gap-2">
+  <Layers className="text-primary" />
+  <div>
+    <p className="text-xs text-slate-500">Categories</p>
+    <p className="text-lg font-black">{categoriesCount}</p>
+  </div>
+</div>
+```
+
+- [ ] **Step 2: Import StatCard component at top of file**
+
+Add to imports:
+```tsx
+import StatCard from '@/components/StatCard';
+```
+
+(Adjust import path based on actual file location)
+
+- [ ] **Step 3: Replace Categories stat display with StatCard**
+
+Find the Categories display section and replace with:
+
+```tsx
+<StatCard 
+  label="Categories" 
+  value={categoriesCount} 
+  icon={Layers}
+/>
+```
+
+Ensure `Layers` icon is imported from lucide-react (should already be if used previously).
+
+- [ ] **Step 4: Replace Item Types stat display with StatCard**
+
+Find the Item Types display section and replace with:
+
+```tsx
+<StatCard 
+  label="Item Types" 
+  value={itemTypesCount} 
+  icon={Package}
+/>
+```
+
+Ensure `Package` icon is imported from lucide-react (standard Lucide icon for item types).
+
+- [ ] **Step 5: Replace Total Boxes stat display with StatCard**
+
+Find the Total Boxes display section and replace with:
+
+```tsx
+<StatCard 
+  label="Total Boxes" 
+  value={totalBoxesCount} 
+  icon={Box}
+/>
+```
+
+Ensure `Box` icon is imported from lucide-react.
+
+- [ ] **Step 6: Verify all three stat cards are now using StatCard component**
+
+Check that the Inventory page displays three stat cards in a consistent layout.
+
+- [ ] **Step 7: Commit the changes**
+
+```bash
+git add frontend/app/inventory/page.tsx
+git commit -m "fix: refactor Inventory page stat cards to use StatCard component
+
+- Replace Categories, Item Types, Total Boxes with StatCard
+- Fixes mobile content overflow with two-column flexbox layout
+- Responsive font sizing for mobile/desktop
+- Label truncation for long text"
+```
+
+---
+
+## Task 3: Update Logs Page Stat Cards
+
+**Files:**
+- Modify: `frontend/app/logs/page.tsx`
+
+- [ ] **Step 1: Read the current logs page to find stat card implementations**
+
+Look for "Total Events" or similar stat display with a count.
+
+- [ ] **Step 2: Import StatCard component**
+
+Add to imports:
+```tsx
+import StatCard from '@/components/StatCard';
+```
+
+- [ ] **Step 3: Replace Total Events stat display with StatCard**
+
+Find the Total Events display section and replace with:
+
+```tsx
+<StatCard 
+  label="Total Events" 
+  value={totalEventsCount} 
+  icon={LogSquare}
+/>
+```
+
+Ensure `LogSquare` icon is imported from lucide-react (or use `FileText`, `ListChecks`, or other appropriate icon if LogSquare doesn't exist).
+
+- [ ] **Step 4: Verify the stat card displays correctly**
+
+Check that the Logs page displays the Total Events stat in the new layout.
+
+- [ ] **Step 5: Commit the changes**
+
+```bash
+git add frontend/app/logs/page.tsx
+git commit -m "fix: refactor Logs page stat cards to use StatCard component
+
+- Replace Total Events display with StatCard
+- Fixes mobile content overflow with responsive layout
+- Consistent styling with Inventory page"
+```
+
+---
+
+## Task 4: Update Admin Page Stat Cards
+
+**Files:**
+- Modify: `frontend/app/admin/page.tsx`
+
+- [ ] **Step 1: Read the current admin page to find stat card implementations**
+
+Look for any label + number stat displays (e.g., "Users", "Sessions", "Audit Logs", etc.).
+
+- [ ] **Step 2: Import StatCard component**
+
+Add to imports:
+```tsx
+import StatCard from '@/components/StatCard';
+```
+
+- [ ] **Step 3: Replace all stat displays with StatCard**
+
+For each stat display on the Admin page, replace with:
+
+```tsx
+<StatCard 
+  label="[Stat Label]" 
+  value={[Count Variable]} 
+  icon={[AppropriateIcon]}
+/>
+```
+
+Example (if there's a "Users" stat):
+```tsx
+<StatCard 
+  label="Users" 
+  value={usersCount} 
+  icon={Users}
+/>
+```
+
+Map appropriate Lucide icons to each stat:
+- Users → `Users`
+- Sessions → `Zap` or `Activity`
+- Audit Logs → `LogSquare` or `FileText`
+- Admins → `Shield`
+- Active Sessions → `Activity`
+
+- [ ] **Step 4: Verify all admin stat cards are updated**
+
+Check that the Admin page displays all stats with consistent StatCard styling.
+
+- [ ] **Step 5: Commit the changes**
+
+```bash
+git add frontend/app/admin/page.tsx
+git commit -m "fix: refactor Admin page stat cards to use StatCard component
+
+- Replace all stat displays with StatCard
+- Fixes mobile content overflow with responsive layout
+- Consistent styling across all admin stats"
+```
+
+---
+
+## Task 5: Test on Mobile Viewport
+
+**Files:**
+- Test: All three pages (Inventory, Logs, Admin)
+
+- [ ] **Step 1: Start the development server**
+
+```bash
+./start_server.sh
+```
+
+Expected: Frontend runs on `http://localhost:8907`
+
+- [ ] **Step 2: Open browser DevTools and set mobile viewport**
+
+1. Open DevTools (F12 or Cmd+Shift+I)
+2. Toggle Device Toolbar (Cmd+Shift+M or Ctrl+Shift+M)
+3. Set to iPhone SE (375px) or iPhone 12 (390px)
+
+- [ ] **Step 3: Test Inventory page on mobile**
+
+Navigate to Inventory page.
+Verify:
+- ✓ "Categories 2" — Label on left, number on right, no overflow
+- ✓ "Item Types 6" — Label on left, number on right, no overflow
+- ✓ "Total Boxes 2" — Label on left, number on right, no overflow
+- ✓ All text is visible (not cut off)
+- ✓ Cards are properly padded
+
+- [ ] **Step 4: Test Logs page on mobile**
+
+Navigate to Logs page.
+Verify:
+- ✓ "Total Events [number]" — Label and number both visible, no overflow
+- ✓ Text formatting is correct
+
+- [ ] **Step 5: Test Admin page on mobile**
+
+Navigate to Admin page.
+Verify:
+- ✓ All stat cards display correctly without overflow
+- ✓ Labels and numbers are properly aligned
+
+- [ ] **Step 6: Test on different mobile widths**
+
+Resize browser to test at:
+- 320px (iPhone SE smallest)
+- 375px (iPhone SE)
+- 390px (iPhone 12)
+- 430px (iPhone 14 Pro Max)
+
+Verify no overflow occurs and layout remains stable.
+
+- [ ] **Step 7: Test on tablet and desktop**
+
+Resize to:
+- 768px (tablet) — verify `md:` breakpoint applies
+- 1024px (desktop) — verify `lg:` breakpoint applies
+
+- [ ] **Step 8: Test with long labels**
+
+(If possible, temporarily update a label to test truncation)
+Example: `<StatCard label="Total Events in System Very Long Name" value={42} />`
+
+Verify: Label shows ellipsis ("Total Events in System...") and doesn't overflow.
+
+- [ ] **Step 9: No test failures**
+
+Run any existing tests to ensure no regressions:
+
+```bash
+npm run test
+```
+
+Expected: All tests pass (or maintain same pass rate as before)
+
+- [ ] **Step 10: Commit test verification notes (optional)**
+
+```bash
+git add .
+git commit -m "test: verify stat card responsive layout on mobile viewports
+
+- iPhone SE (375px): No overflow ✓
+- iPhone 12 (390px): No overflow ✓
+- iPhone 14 Pro Max (430px): No overflow ✓
+- Tablet (768px): Desktop styling ✓
+- Desktop (1024px): Large text ✓
+- Long label truncation: Ellipsis works ✓"
+```
+

+
+## Task 6: Final Verification & Documentation Update
+
+**Files:**
+- Review: All modified pages
+- Update: `dev_docs/SESSION_STATE.md` (handover)
+
+- [ ] **Step 1: Verify all commits are in place**
+
+```bash
+git log --oneline -6
+```
+
+Expected output includes:
+- `feat: create reusable StatCard component...`
+- `fix: refactor Inventory page stat cards...`
+- `fix: refactor Logs page stat cards...`
+- `fix: refactor Admin page stat cards...`
+- (optional) `test: verify stat card responsive layout...`
+
+- [ ] **Step 2: Check for any remaining inline stat displays**
+
+Search the codebase for any remaining old-style stat displays:
+
+```bash
+grep -r "text-xs text-slate-500" frontend/app --include="*.tsx" | grep -i "categor\|item\|box\|event\|user\|session"
+```
+
+If found, replace with StatCard component.
+
+- [ ] **Step 3: Update SESSION_STATE.md handover**
+
+Add to `dev_docs/SESSION_STATE.md`:
+
+```markdown
+### Mobile Stat Cards Responsive Fix (Completed)
+
+**Issue:** Stat card content overflowed outside card boundaries on iPhone mobile screens (< 640px).
+
+**Solution:** Created reusable `StatCard` component with two-column flexbox layout:
+- Label (left, flexible, truncates if long)
+- Number (right, fixed, never wraps)
+- Responsive font sizes: `text-sm md:text-base` (label), `text-lg md:text-xl` (number)
+
+**Pages Fixed:**
+- ✓ Inventory page (Categories, Item Types, Total Boxes)
+- ✓ Logs page (Total Events)
+- ✓ Admin page (all stat displays)
+
+**Verification:**
+- ✓ iPhone SE (375px): No overflow
+- ✓ iPhone 12 (390px): No overflow
+- ✓ Tablet/Desktop: Responsive scaling works
+- ✓ Long labels: Truncate with ellipsis
+- ✓ All tests pass
+
+**Files Changed:**
+- Created: `frontend/components/StatCard.tsx`
+- Modified: `frontend/app/inventory/page.tsx`
+- Modified: `frontend/app/logs/page.tsx`
+- Modified: `frontend/app/admin/page.tsx`
+
+**Next Steps:** Deploy to remote server and verify on real iPhone device if possible.
+```
+
+- [ ] **Step 4: Commit the handover update**
+
+```bash
+git add dev_docs/SESSION_STATE.md
+git commit -m "docs: update session state - mobile stat cards responsive fix complete
+
+- StatCard component created and integrated
+- All three pages (Inventory, Logs, Admin) updated

+```
+
+- [ ] **Step 5: Verify no uncommitted changes**
+
+```bash
+git status
+```
+
+Expected: `working tree clean`
+
+- [ ] **Step 6: Review the spec coverage one final time**
