+# 🌿 CannaManage — Visual Tour (Sprint 4)
+
+**Generated:** 2026-06-12 | **Commit:** `fe6e96d` | **19 Screenshots** | **Dark + Light Mode**
+
+---
+
+## 🔐 Chapter 1: Authentication
+
+### Admin Login
+
+The admin login page greets club administrators with a clean, branded form. Email + password fields, CannaManage branding, and i18n-ready labels. Error states are handled gracefully when credentials fail.
+
+| Dark Mode | Light Mode |
+|-----------|------------|
+| ![Admin Login — Dark](screenshots/01-login-dark.png) | ![Admin Login — Light](screenshots/01-login-light.png) |
+
+---
+
+### Member Portal Login
+
+Members get a simplified login experience — same form but under the portal layout (top navigation instead of sidebar). This keeps the two user groups visually separated.
+
+| Dark Mode | Light Mode |
+|-----------|------------|
+| ![Portal Login — Dark](screenshots/02-portal-login-dark.png) | ![Portal Login — Light](screenshots/02-portal-login-light.png) |
+
+---
+
+## 📊 Chapter 2: Admin Dashboard
+
+### Club Overview
+
+After login, admins land on the main dashboard. Four KPI cards at the top (active members, monthly distributions, stock weight, open recalls), a stock trend chart, recent distributions table, and quick action buttons.
+
+![Dashboard — Dark Mode](screenshots/03-dashboard-dark.png)
+
+---
+
+### Member Management
+
+The members page uses TanStack Table with full search, column sorting, pagination, and status badges (Active 🟢, Suspended 🟡, Expelled 🔴). Click any row to edit.
+
+![Members — Dark Mode](screenshots/04-members-dark.png)
+
+---
+
+## 📦 Chapter 3: Distribution & Compliance
+
+### Distribution History
+
+All past distributions with lock icons (🔒) indicating immutable audit records. Filter by date range or member. A "today" summary card shows daily totals.
+
+![Distributions — Dark Mode](screenshots/05-distributions-dark.png)
+
+---
+
+### New Distribution — Multi-Step Form
+
+The 4-step distribution form enforces CanG compliance at each stage:
+1. **Select member** — search + status check
+2. **Quota check** — shows remaining daily (25g) and monthly (50g/30g) with color coding
+3. **Batch + amount** — select from available batches, enter grams
+4. **Confirm** — review all details before recording
+
+![New Distribution — Dark Mode](screenshots/06-distribution-new-dark.png)
+
+---
+
+## 🌱 Chapter 4: Stock Management
+
+### Batch Overview
+
+Bar chart showing stock levels by strain, summary cards (total weight, batch count, pending recalls), and a table with recall buttons. Recalled batches are visually marked.
+
+![Stock — Dark Mode](screenshots/07-stock-dark.png)
+
+---
+
+### Add New Batch
+
+Form to register new cannabis batches: strain selector, THC/CBD percentages, supplier info, harvest date, weight. All required for traceability.
+
+![New Batch — Dark Mode](screenshots/08-stock-new-dark.png)
+
+---
+
+## 📋 Chapter 5: Compliance Reports
+
+### Report Center
+
+Three report cards: Monthly Summary, Member List, and Recall Report. Each has download (PDF/CSV) and preview options. Reports are designed for regulatory submissions.
+
+![Reports — Dark Mode](screenshots/09-reports-dark.png)
+
+---
+
+## 👤 Chapter 6: Member Portal
+
+### Quota Dashboard
+
+Members see their remaining quota as radial SVG progress rings — daily and monthly. Color-coded: green (<50%), amber (50-80%), red (>80%). Under-21 members see the reduced 30g/month limit.
+
+| Dark Mode | Light Mode |
+|-----------|------------|
+| ![Portal Dashboard — Dark](screenshots/10-portal-dashboard-dark.png) | ![Portal Dashboard — Light](screenshots/10-portal-dashboard-light.png) |
+
+---
+
+### My Distribution History
+
+Members can review their own past distributions. Month filter, lock icons confirming immutability. No edit/delete possible — read-only audit trail.
+
+| Dark Mode | Light Mode |
+|-----------|------------|
+| ![Portal History — Dark](screenshots/11-portal-history-dark.png) | ![Portal History — Light](screenshots/11-portal-history-light.png) |
+
+---
+
+### Profile & Settings
+
+Personal information (read-only, managed by admin), password change form, and preferences (language selector, theme toggle). Members can switch between dark/light mode here.
+
+| Dark Mode | Light Mode |
+|-----------|------------|
+| ![Portal Profile — Dark](screenshots/12-portal-profile-dark.png) | ![Portal Profile — Light](screenshots/12-portal-profile-light.png) |
+
+---
+
+## 🎨 Theme Comparison
+
+The entire application supports both dark and light mode with a single click toggle:
+
+- **Dark** (default): `#0D1117` background, `#2ECC71` green accent — cannabis club aesthetic
+- **Light**: `#FAFBFC` background, `#1B7A3D` darker green — for outdoor/mobile readability
+
+---
+
+## 📐 Tech Behind the Screenshots
+
+- **Tool:** Playwright (Chromium, 1280×720 viewport)
+- **Method:** Automated E2E script (`e2e/screenshot-tour.spec.ts`)
+- **Auth:** Mock backend returning valid JWT session
+- **Pages captured:** 12 unique routes × 2 themes (where auth allowed)
+- **Total screenshots:** 19 PNG files (~1.2MB total)
+
+To regenerate:
+```bash
+cd cannamanage-frontend
+node e2e/mock-backend.mjs &   # start mock auth backend
+pnpm dev &                     # start Next.js dev server
+pnpm exec playwright test e2e/screenshot-tour.spec.ts
+```
