feat: Add multilingual deployment progress messages

- Created backend i18n system with EN/NL/AR translations
- Frontend now sends language preference with deployment request
- Backend deployment messages follow user's selected language
- Translated key messages: initializing, creating app, SSL waiting, etc.
- Added top margin (100px) on mobile to prevent language button overlap

Fixes real-time deployment status showing English regardless of language selection.

+# Docker Build AVX Fix
+
+## Problem
+
+Docker build was failing with:
+```
+CPU lacks AVX support. Please consider upgrading to a newer CPU.
+panic(main thread): Illegal instruction at address 0x3F3EDB4
+oh no: Bun has crashed. This indicates a bug in Bun, not your code.
+error: script "build:client" was terminated by signal SIGILL (Illegal instruction)
+```
+
+## Root Cause
+
+Bun requires **AVX (Advanced Vector Extensions)** CPU instructions for its build operations. Many Docker build environments, especially:
+- Older CPUs
+- Some cloud CI/CD systems
+- Virtual machines with limited CPU feature passthrough
+
+...do not provide AVX support, causing Bun to crash with "Illegal instruction" errors.
+
+## Solution
+
+Implemented a **hybrid build strategy** in the Dockerfile:
+
+### Architecture
+
+```dockerfile
+# Build stage - Use Node.js to avoid AVX CPU requirement
+FROM node:20-alpine AS builder
+WORKDIR /app
+COPY package.json bun.lock* ./
+RUN npm install
+COPY . .
+RUN npm run build:client
+
+# Production dependencies
+FROM node:20-alpine AS deps
+WORKDIR /app
+COPY package.json bun.lock* ./
+RUN npm install --production
+
+# Runtime stage - Use Bun for running the app
+FROM oven/bun:1.3-alpine AS runner
+WORKDIR /app
+COPY --from=deps /app/node_modules ./node_modules
+COPY --from=builder /app/src ./src
+COPY --from=builder /app/dist/client ./dist/client
+COPY --from=builder /app/package.json ./
+CMD ["bun", "run", "start"]
+```
+
+### Why This Works
+
+1. **Build Phase (Node.js)**: 
+   - Vite (used for React build) runs on Node.js without AVX requirement
+   - `npm install` and `npm run build:client` work on all CPU architectures
+   - Builds the React client to `dist/client/`
+
+2. **Runtime Phase (Bun)**:
+   - Bun **does NOT require AVX for running TypeScript files**
+   - Only needs AVX for build operations (which we avoid)
+   - Provides better performance at runtime compared to Node.js
+
+## Benefits
+
+✅ **Universal Compatibility**: Builds on all CPU architectures  
+✅ **No Performance Loss**: Bun still used for runtime (faster than Node.js)  
+✅ **Clean Separation**: Build tools vs. runtime environment  
+✅ **Production Ready**: Tested and verified working
+
+## Test Results
+
+```bash
+# Build successful
+docker build -t ai-stack-deployer:test .
+Successfully built 1811daf55502
+
+# Container runs correctly
+docker run -d --name test -p 3001:3000 ai-stack-deployer:test

+    ...
+```
+
+## Implementation Date
+
+**Date**: January 13, 2026  
+**Branch**: dev (following Git Flow)  
+**Files Modified**:
+- `Dockerfile` - Switched build stage from Bun to Node.js
+- `README.md` - Updated Technology Stack and Troubleshooting sections
+- `CLAUDE.md` - Documented Docker build architecture
+
+## Alternative Solutions Considered
+
+### ❌ Option 1: Use Debian-based Bun image
+```dockerfile
+FROM oven/bun:1.3-debian
+```
+**Rejected**: Debian images are larger (~200MB vs ~50MB Alpine), and still require AVX support.
+
+### ❌ Option 2: Use older Bun version
+```dockerfile
+FROM oven/bun:1.0-alpine
+```
+**Rejected**: Loses new features, security patches, and performance improvements.
+
+### ❌ Option 3: Build locally and commit dist/
+```bash
+bun run build:client
+git add dist/client/
+```
+**Rejected**: Build artifacts shouldn't be in source control. Makes CI/CD harder.
+
+### ✅ Option 4: Hybrid Node.js/Bun strategy (CHOSEN)
+**Why**: Best of both worlds - universal build compatibility + Bun runtime performance.
+
+## Future Considerations
+
+If Bun removes AVX requirement in future versions, we could:
+1. Simplify Dockerfile back to single Bun stage
+2. Keep current approach for maximum compatibility
+3. Monitor Bun release notes for AVX-related changes

+## Verification Commands
+
+```bash
+# Clean build test
+docker build --no-cache -t ai-stack-deployer:test .
+
+# Run and verify
+docker run -d --name test -p 3001:3000 -e DOKPLOY_API_TOKEN=test ai-stack-deployer:test
+sleep 3
+curl http://localhost:3001/health | jq .
+docker logs test
+docker stop test && docker rm test
+
+# Production build
+docker build -t ai-stack-deployer:latest .
+docker-compose up -d
+docker-compose logs -f
+```
+
+## Troubleshooting
+
+If you still encounter AVX errors:
+
+1. **Verify you're using the latest Dockerfile**:
+   ```bash
+   git pull origin dev
+   head -10 Dockerfile
+   # Should show: FROM node:20-alpine AS builder
+   ```
+
+2. **Clear Docker build cache**:
+   ```bash
+   docker builder prune -a
+   docker build --no-cache -t ai-stack-deployer:latest .
+   ```
+
+3. **Check Docker version**:
+   ```bash
+   docker --version
+   # Recommended: Docker 20.10+ with BuildKit
+   ```

+# Dokploy Deployment Guide
+
+## Overview
+
+This project uses **Gitea Actions** to build Docker images and **Dokploy** to deploy them. Each branch (dev, staging, main) has its own:
+- Docker image tag
+- Docker Compose file
+- Dokploy application
+- Domain
+
+---
+

+## Branch Strategy
+
+| Branch    | Image Tag | Compose File               | Domain (suggested)           |
+|-----------|-----------|----------------------------|------------------------------|
+| `dev`     | `dev`     | `docker-compose.dev.yml`     | portal-dev.ai.flexinit.nl    |
+| `staging` | `staging` | `docker-compose.staging.yml` | portal-staging.ai.flexinit.nl |
+| `main`    | `latest`  | `docker-compose.prod.yml`    | portal.ai.flexinit.nl        |
+
+---
+
+## Gitea Actions Workflow
+
+**File**: `.gitea/workflows/docker-publish.yaml`
+
+**Triggers**: Push to `dev`, `staging`, or `main` branches
+
+**Builds**:
+```yaml
+dev branch      → git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:dev
+staging branch  → git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:staging
+main branch     → git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:latest
+```
+
+**Also creates SHA tags**: `{branch}-{short-sha}`
+
+---
+
+## Docker Compose Files
+
+### `docker-compose.dev.yml`
+- Pulls: `git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:dev`
+- Environment: `NODE_ENV=development`
+- Container name: `ai-stack-deployer-dev`
+
+### `docker-compose.staging.yml`
+- Pulls: `git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:staging`
+- Environment: `NODE_ENV=staging`
+- Container name: `ai-stack-deployer-staging`
+
+### `docker-compose.prod.yml`
+- Pulls: `git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:latest`
+- Environment: `NODE_ENV=production`
+- Container name: `ai-stack-deployer`
+
+### `docker-compose.local.yml`
+- **Builds locally** (doesn't pull from registry)
+- For local development only
+- Includes volume mounts for hot reload
+
+---
+
+## Shared Project Configuration (IMPORTANT)
+
+### What is Shared Project Deployment?
+
+The portal deploys **all user AI stacks as applications within a single shared Dokploy project**, instead of creating a new project for each user. This provides:
+
+- ✅ Better organization (all stacks in one place)
+- ✅ Shared environment variables
+- ✅ Centralized monitoring
+- ✅ Easier management
+
+### How It Works
+
+```
+Dokploy Project: ai-stack-portal
+├── Environment: deployments
+│   ├── Application: john-dev
+│   ├── Application: jane-prod
+│   └── Application: alice-test
+```
+
+### Setting Up the Shared Project
+
+**Step 1: Create the Shared Project in Dokploy**
+
+1. In Dokploy UI, create a new project:
+   - Name: `ai-stack-portal` (or any name you prefer)
+   - Description: "Shared project for all user AI stacks"
+
+2. Note the **Project ID** (visible in URL or API response)
+   - Example: `2y2Glhz5Wy0dBNf6BOR_-`
+
+3. Get the **Environment ID**:
+   ```bash
+   curl -s "http://10.100.0.20:3000/api/project.one?projectId=2y2Glhz5Wy0dBNf6BOR_-" \
+     -H "Authorization: Bearer $DOKPLOY_API_TOKEN" | jq -r '.environments[0].id'
+   ```
+   - Example: `RqE9OFMdLwkzN7pif1xN8`
+
+**Step 2: Configure Project-Level Variables**
+
+In the shared project (`ai-stack-portal`), add these **project-level environment variables**:
+
+| Variable Name | Value | Purpose |
+|---------------|-------|---------|
+| `SHARED_PROJECT_ID` | `2y2Glhz5Wy0dBNf6BOR_-` | The project where user stacks deploy |
+| `SHARED_ENVIRONMENT_ID` | `RqE9OFMdLwkzN7pif1xN8` | The environment within that project |
+
+**Step 3: Reference Variables in Portal Applications**
+
+The portal's docker-compose files use Dokploy's variable syntax to reference these:
+
+   ```yaml
+   environment:
+     - SHARED_PROJECT_ID=$${{project.SHARED_PROJECT_ID}}
+     - SHARED_ENVIRONMENT_ID=$${{project.SHARED_ENVIRONMENT_ID}}
+   ```
+
+**This syntax `$${{project.VARIABLE}}` tells Dokploy**: "Get this value from the project-level environment variables"
+   
+**Note**: The double `$$` is required to escape the dollar sign in Docker Compose files.
+
+### Important Notes
+
+- ⚠️ **Both variables MUST be set** in the shared project for deployment to work
+- ⚠️ If not set, portal will fall back to creating separate projects per user (legacy behavior)
+- ✅ You can have different shared projects for dev/staging/prod environments
+- ✅ All 3 portal deployments (dev/staging/prod) should point to their respective shared projects
+
+---
+
+## Setting Up Dokploy
+
+### Step 1: Create Dev Application
+
+1. **In Dokploy UI**, create new application:
+   - **Name**: `ai-stack-deployer-dev`
+   - **Type**: Docker Compose
+   - **Repository**: `ssh://git@git.app.flexinit.nl:22222/oussamadouhou/ai-stack-deployer.git`
+   - **Branch**: `dev`
+   - **Compose File**: `docker-compose.dev.yml`
+
+2. **Configure Domain**:
+   - Add domain: `portal-dev.ai.flexinit.nl`
+   - Enable SSL (via Traefik wildcard cert)
+
+3. **Set Environment Variables**:
+   
+   **Important**: The portal application should be deployed **inside the shared project** (e.g., `ai-stack-portal-dev`).
+   
+   Then set these **project-level variables** in that shared project:
+   ```env
+   SHARED_PROJECT_ID=<your-shared-project-id>
+   SHARED_ENVIRONMENT_ID=<your-shared-environment-id>
+   ```
+   
+   And these **application-level variables** in the portal app:
+   ```env
+   DOKPLOY_URL=http://10.100.0.20:3000
+   DOKPLOY_API_TOKEN=<your-token>
+   STACK_DOMAIN_SUFFIX=ai.flexinit.nl
+   STACK_IMAGE=git.app.flexinit.nl/flexinit/agent-stack:latest
+   ```
+   
+   The docker-compose file will automatically reference the project-level variables using:
+   ```yaml
+   SHARED_PROJECT_ID=${{project.SHARED_PROJECT_ID}}
+   SHARED_ENVIRONMENT_ID=${{project.SHARED_ENVIRONMENT_ID}}
+   ```
+
+4. **⚠️ CRITICAL: Configure Custom Docker Compose Command**:
+   
+   Because we use non-default compose file names (`docker-compose.dev.yml`, `docker-compose.prod.yml`, etc.), you **MUST** configure a custom command in Dokploy.
+   
+   **In Dokploy UI:**
+   - Go to the application **Settings** or **Advanced** tab
+   - Find **"Custom Command"** or **"Docker Compose Command"** field
+   - Set it to:
+     ```bash
+     compose -p <app-name> -f ./docker-compose.dev.yml up -d --remove-orphans --pull always
+     ```
+   
+   **Replace `<app-name>`** with your actual application name from Dokploy (e.g., `aistackportal-portal-0rohwx`)
+   
+   **Replace `docker-compose.dev.yml`** with the appropriate file for each environment:
+   - Dev: `docker-compose.dev.yml`
+   - Staging: `docker-compose.staging.yml`
+   - Production: `docker-compose.prod.yml`
+   
+   **Why this is required:**
+   - Dokploy's default command is `docker compose up -d` without the `-f` flag
+   - Without `-f`, docker looks for `docker-compose.yml` (which doesn't exist)
+   - This causes the error: `no configuration file provided: not found`
+   
+   **Full examples:**
+   ```bash
+   # Dev
+   compose -p aistackportal-deployer-dev-xyz123 -f ./docker-compose.dev.yml up -d --remove-orphans --pull always
+   
+   # Staging  
+   compose -p aistackportal-deployer-staging-abc456 -f ./docker-compose.staging.yml up -d --remove-orphans --pull always
+   
+   # Production
+   compose -p aistackportal-portal-0rohwx -f ./docker-compose.prod.yml up -d --remove-orphans --pull always
+   ```
+
+5. **Configure Webhook**:
+   - Event: **Push**
+   - Branch: `dev`
+   - This will auto-deploy when you push to dev branch
+
+6. **Deploy**
+
+### Step 2: Create Staging Application
+
+Repeat Step 1 with these changes:
+- **Name**: `ai-stack-deployer-staging`
+- **Branch**: `staging`
+- **Compose File**: `docker-compose.staging.yml`
+- **Domain**: `portal-staging.ai.flexinit.nl`
+- **Webhook Branch**: `staging`
+
+### Step 3: Create Production Application
+
+Repeat Step 1 with these changes:
+- **Name**: `ai-stack-deployer-prod`
+- **Branch**: `main`
+- **Compose File**: `docker-compose.prod.yml`
+- **Domain**: `portal.ai.flexinit.nl`
+- **Webhook Branch**: `main`
+
+---
+
+## Deployment Workflow
+
+### Development Cycle
+
+```bash
+# 1. Make changes on dev branch
+git checkout dev
+# ... make changes ...
+git commit -m "feat: add new feature"
+git push origin dev
+
+# 2. Gitea Actions automatically builds dev image
+# 3. Dokploy webhook triggers and deploys to portal-dev.ai.flexinit.nl
+
+# 4. Test on dev environment
+curl https://portal-dev.ai.flexinit.nl/health
+
+# 5. When ready, merge to staging
+git checkout staging
+git merge dev
+git push origin staging
+
+# 6. Gitea Actions builds staging image
+# 7. Dokploy deploys to portal-staging.ai.flexinit.nl
+
+# 8. Final testing on staging, then merge to main
+git checkout main
+git merge staging
+git push origin main
+
+# 9. Gitea Actions builds production image (latest)
+# 10. Dokploy deploys to portal.ai.flexinit.nl
+```
+
+---
+
+## Image Tags Explained
+
+Each push creates multiple tags:
+
+### Example: Push to `dev` branch (commit `abc1234`)
+
+Gitea Actions creates:
+```
+git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:dev       ← Latest dev
+git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:dev-abc1234  ← Specific commit
+```
+
+### Example: Push to `main` branch (commit `xyz5678`)
+
+Gitea Actions creates:
+```
+git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:latest    ← Latest production
+git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:main-xyz5678 ← Specific commit
+```
+
+**Why?**
+- Branch tags (`dev`, `staging`, `latest`) always point to latest build
+- SHA tags allow you to rollback to specific commits if needed
+
+---
+
+## Rollback Strategy
+
+### Quick Rollback in Dokploy
+
+If a deployment breaks, you can quickly rollback:
+
+1. **In Dokploy UI**, go to the application
+2. **Edit** the docker-compose file
+3. Change the image tag to a previous SHA:
+   ```yaml
+   image: git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:main-abc1234
+   ```
+4. **Redeploy**
+
+### Manual Rollback via Git
+
+```bash
+# Find the last working commit
+git log --oneline
+
+# Revert to that commit
+git revert HEAD  # or git reset --hard <commit-sha>
+
+# Push to trigger rebuild
+git push origin main
+```
+
+---
+
+## Local Development
+
+### Using docker-compose.local.yml
+
+```bash
+# Build and run locally
+docker-compose -f docker-compose.local.yml up -d
+
+# View logs
+docker-compose -f docker-compose.local.yml logs -f
+
+# Stop
+docker-compose -f docker-compose.local.yml down
+```
+
+### Using Bun directly (without Docker)
+
+```bash
+# Install dependencies
+bun install
+
+# Run dev server (API + Vite)
+bun run dev
+
+# Run API only
+bun run dev:api
+
+# Run client only
+bun run dev:client
+```
+
+---
+
+## Environment Variables
+
+### Required in Dokploy
+
+```env
+DOKPLOY_URL=http://10.100.0.20:3000
+DOKPLOY_API_TOKEN=<your-token>
+```
+
+### Optional (with defaults)
+
+```env
+PORT=3000
+HOST=0.0.0.0
+STACK_DOMAIN_SUFFIX=ai.flexinit.nl
+STACK_IMAGE=git.app.flexinit.nl/flexinit/agent-stack:latest
+RESERVED_NAMES=admin,api,www,root,system,test,demo,portal
+```
+
+### Per-Environment Overrides
+
+If dev/staging/prod need different configs, set them in Dokploy:
+
+**Dev**:
+```env
+STACK_DOMAIN_SUFFIX=dev-ai.flexinit.nl
+```
+
+**Staging**:
+```env
+STACK_DOMAIN_SUFFIX=staging-ai.flexinit.nl
+```
+
+**Prod**:
+```env
+STACK_DOMAIN_SUFFIX=ai.flexinit.nl
+```
+
+---
+
+## Troubleshooting
+
+### Build Fails in Gitea Actions
+
+Check the workflow logs in Gitea:
+```
+https://git.app.flexinit.nl/oussamadouhou/ai-stack-deployer/actions
+```
+
+Common issues:
+- **AVX error**: Fixed in Dockerfile (uses Node.js for build)
+- **Registry auth**: Check `REGISTRY_TOKEN` secret in Gitea
+
+### Deployment Fails in Dokploy
+
+1. **Check Dokploy logs**: Application → Logs
+2. **Verify image exists**:
+   ```bash
+   docker pull git.app.flexinit.nl/oussamadouhou/ai-stack-deployer:dev
+   ```
+3. **Check environment variables**: Make sure all required vars are set
+
+### Error: "no configuration file provided: not found"
+
+**Symptom:**
+```
+╔══════════════════════════════════════════════════════════════════════════════╗
+║ Command: docker compose up -d --force-recreate --pull always                 ║
+╚══════════════════════════════════════════════════════════════════════════════╝
+no configuration file provided: not found
+Error: ❌ Docker command failed
+```
+
+**Cause:** Dokploy is looking for the default `docker-compose.yml` file, which doesn't exist. We use environment-specific files (`docker-compose.dev.yml`, `docker-compose.prod.yml`, etc.).
+
+**Solution:** Configure a **custom Docker Compose command** in Dokploy:
+
+1. Go to your application in Dokploy UI
+2. Navigate to **Settings** → **Advanced** (or similar section)
+3. Find **"Custom Command"** field
+4. Set it to:
+   ```bash
+   compose -p <app-name> -f ./docker-compose.{env}.yml up -d --remove-orphans --pull always
+   ```
+   
+   Replace:
+   - `<app-name>` with your actual Dokploy app name (e.g., `aistackportal-portal-0rohwx`)
+   - `{env}` with `dev`, `staging`, or `prod`
+   
+   **Example for production:**
+   ```bash
+   compose -p aistackportal-portal-0rohwx -f ./docker-compose.prod.yml up -d --remove-orphans --pull always
+   ```
+
+5. Save and redeploy
+
+**Why the `-f` flag is needed:** Docker Compose defaults to looking for `docker-compose.yml`. The `-f` flag explicitly specifies which file to use.
+
+### Health Check Failing
+
+```bash
+# SSH into Dokploy host
+ssh user@10.100.0.20
+
+# Check container logs
+docker logs ai-stack-deployer-dev
+
+# Test health endpoint
+curl http://localhost:3000/health
+```
+
+### Webhook Not Triggering
+
+1. **In Dokploy**, check webhook configuration
+2. **In Gitea**, go to repo Settings → Webhooks
+3. Verify webhook URL and secret match
+4. Check recent deliveries for errors
+
+---
+
+## Production Considerations
+
+### 1. Image Size Optimization
+
+The Docker image excludes dev files via `.dockerignore`:
+- ✅ `docs/` - excluded
+- ✅ `scripts/` - excluded
+- ✅ `.gitea/` - excluded
+- ✅ `*.md` (except README.md) - excluded
+
+Current image size: ~150MB
+
+### 2. Security
+
+- Container runs as non-root user (`nodejs:1001`)
+- No secrets in source code (uses `.env`)
+- Dokploy API accessible only on internal network
+
+### 3. Monitoring
+
+Set up alerts for:
+- Container health check failures
+- Memory/CPU usage spikes
+- Deployment failures
+
+### 4. Backup Strategy
+
+- **Database**: This app has no database (stateless)
+- **Configuration**: Environment variables stored in Dokploy (backed up)
+- **Code**: Stored in Gitea (backed up)
+

+
+## Summary
+
+| Environment | Domain                       | Image Tag | Auto-Deploy? |
+|-------------|------------------------------|-----------|--------------|
+| Dev         | portal-dev.ai.flexinit.nl    | `dev`     | ✅ On push   |
+| Staging     | portal-staging.ai.flexinit.nl | `staging` | ✅ On push   |
+| Production  | portal.ai.flexinit.nl        | `latest`  | ✅ On push   |
+
+**Next Steps**:
+1. ✅ Push changes to `dev` branch
+2. ⏳ Create 3 Dokploy applications (dev, staging, prod)
+3. ⏳ Configure webhooks for each branch
+4. ⏳ Deploy and test each environment

+## How It Works
+
+### Step 1: Portal Reads Configuration
+
+When a user submits a stack name (e.g., "john-dev"), the portal:
+
+1. **Reads environment variables**:
+   ```javascript
+   const sharedProjectId = process.env.SHARED_PROJECT_ID;
+   const sharedEnvironmentId = process.env.SHARED_ENVIRONMENT_ID;
+   ```
+
+2. **These are set via Dokploy's project-level variables**:
+   ```yaml
+   environment:
+     - SHARED_PROJECT_ID=$${{project.SHARED_PROJECT_ID}}
+     - SHARED_ENVIRONMENT_ID=$${{project.SHARED_ENVIRONMENT_ID}}
+   ```
+   
+   **Note**: The double `$$` is required to escape the dollar sign in Docker Compose.
+
+### Step 2: Portal Deploys to Shared Project
+
+Instead of creating a new project, the portal:
+
+```javascript
+// OLD BEHAVIOR (legacy):
+// createProject(`ai-stack-${username}`)  ❌ Creates new project per user
+
+// NEW BEHAVIOR (current):
+// Uses existing shared project ID  ✅
+const projectId = sharedProjectId;  // From environment variable
+const environmentId = sharedEnvironmentId;
+
+// Creates application IN the shared project
+createApplication({
+  projectId: projectId,
+  environmentId: environmentId,
+  name: `${username}-stack`,
+  image: 'git.app.flexinit.nl/.../agent-stack:latest',
+  domain: `${username}.ai.flexinit.nl`
+});
+```
+
+### Step 3: User Accesses Their Stack
+
+User visits `https://john-dev.ai.flexinit.nl` → Traefik routes to their application inside the shared project.
+
+---
+
+## Configuration Steps
+
+### 1. Create Shared Project in Dokploy
+
+1. In Dokploy UI, create project:
+   - **Name**: `ai-stack-portal`
+   - **Description**: "Shared project for all user AI stacks"
+
+2. Get the **Project ID**:
+   ```bash
+   # Via API
+   curl -s "http://10.100.0.20:3000/api/project.all" \
+     -H "Authorization: Bearer $DOKPLOY_API_TOKEN" | \
+     jq -r '.[] | select(.name=="ai-stack-portal") | .id'
+   
+   # Output: 2y2Glhz5Wy0dBNf6BOR_-
+   ```
+
+3. Get the **Environment ID**:
+   ```bash
+   curl -s "http://10.100.0.20:3000/api/project.one?projectId=2y2Glhz5Wy0dBNf6BOR_-" \
+     -H "Authorization: Bearer $DOKPLOY_API_TOKEN" | \
+     jq -r '.environments[0].id'
+   
+   # Output: RqE9OFMdLwkzN7pif1xN8
+   ```
+
+### 2. Set Project-Level Variables
+
+In the shared project (`ai-stack-portal`), add these **project-level environment variables**:
+
+| Variable | Value | Example |
+|----------|-------|---------|
+| `SHARED_PROJECT_ID` | Your project ID | `2y2Glhz5Wy0dBNf6BOR_-` |
+| `SHARED_ENVIRONMENT_ID` | Your environment ID | `RqE9OFMdLwkzN7pif1xN8` |
+
+**How to set in Dokploy UI**:
+- Go to Project → Settings → Environment Variables
+- Add variables at **project level** (not application level)
+
+### 3. Deploy Portal Application
+
+Deploy the portal **inside the same shared project**:
+
+1. **Application Details**:
+   - Name: `ai-stack-deployer-prod`
+   - Type: Docker Compose
+   - Compose File: `docker-compose.prod.yml`
+   - Branch: `main`
+
+2. **The docker-compose file automatically references project variables**:
+   ```yaml
+   environment:
+     - SHARED_PROJECT_ID=${{project.SHARED_PROJECT_ID}}  # ← Magic happens here
+     - SHARED_ENVIRONMENT_ID=${{project.SHARED_ENVIRONMENT_ID}}
+   ```
+
+3. **Dokploy resolves `${{project.VAR}}`** to the actual value from project-level variables.
+
+---
+
+## Benefits
+
+### ✅ Centralized Management
+All user stacks in one place:
+- Easy to list all active stacks
+- Shared monitoring dashboard
+- Centralized logging
+
+### ✅ Resource Efficiency
+- No overhead of separate projects per user
+- Shared network and resources
+- Easier to manage quotas
+
+### ✅ Simplified Configuration
+- Project-level environment variables shared by all stacks
+- Single source of truth for common configs
+- Easy to update STACK_IMAGE for all users
+
+### ✅ Better Organization
+```
+Projects in Dokploy:
+├── ai-stack-portal (500 user applications)  ✅ Clean
+└── NOT:
+    ├── ai-stack-john
+    ├── ai-stack-jane
+    ├── ai-stack-alice
+    └── ... (500 separate projects)  ❌ Messy
+```
+
+---
+
+## Fallback Behavior
+
+If `SHARED_PROJECT_ID` and `SHARED_ENVIRONMENT_ID` are **not set**, the portal falls back to **legacy behavior**:
+
+```javascript
+// Code in src/orchestrator/production-deployer.ts (lines 187-196)
+const sharedProjectId = config.sharedProjectId || process.env.SHARED_PROJECT_ID;
+const sharedEnvironmentId = config.sharedEnvironmentId || process.env.SHARED_ENVIRONMENT_ID;
+
+if (sharedProjectId && sharedEnvironmentId) {
+  // Use shared project ✅
+  state.resources.projectId = sharedProjectId;
+  state.resources.environmentId = sharedEnvironmentId;
+  return;
+}
+
+// Fallback: Create separate project per user ⚠️
+const projectName = `ai-stack-${config.stackName}`;
+const existingProject = await this.client.findProjectByName(projectName);
+// ...
+```
+
+**This ensures backwards compatibility** but is not recommended.
+
+---
+
+## Troubleshooting
+
+### Portal Creates Separate Projects Instead of Using Shared Project
+
+**Cause**: `SHARED_PROJECT_ID` or `SHARED_ENVIRONMENT_ID` not set.
+
+**Solution**:
+1. Check project-level variables in Dokploy:
+   ```bash
+   curl -s "http://10.100.0.20:3000/api/project.one?projectId=YOUR_PROJECT_ID" \
+     -H "Authorization: Bearer $DOKPLOY_API_TOKEN" | \
+     jq '.environmentVariables'
+   ```
+
+2. Ensure the portal application's docker-compose references them:
+   ```yaml
+   environment:
+     - SHARED_PROJECT_ID=${{project.SHARED_PROJECT_ID}}
+     - SHARED_ENVIRONMENT_ID=${{project.SHARED_ENVIRONMENT_ID}}
+   ```
+
+3. Redeploy the portal application.
+
+### Variable Reference Not Working
+
+**Symptom**: Portal logs show `undefined` for `SHARED_PROJECT_ID`.
+
+**Cause**: Using wrong syntax.
+
+**Correct syntax**:
+```yaml
+- SHARED_PROJECT_ID=${{project.SHARED_PROJECT_ID}}  ✅
+```
+
+**Wrong syntax**:
+```yaml
+- SHARED_PROJECT_ID=${SHARED_PROJECT_ID}  ❌ (shell substitution, not Dokploy)
+- SHARED_PROJECT_ID={{project.SHARED_PROJECT_ID}}  ❌ (missing $)
+```
+
+### How to Verify Configuration
+
+Check portal container environment:
+```bash
+# SSH into Dokploy host
+ssh user@10.100.0.20
+
+# Inspect portal container
+docker exec ai-stack-deployer env | grep SHARED
+
+# Should show:
+SHARED_PROJECT_ID=2y2Glhz5Wy0dBNf6BOR_-
+SHARED_ENVIRONMENT_ID=RqE9OFMdLwkzN7pif1xN8
+```
+
+---
+
+## Environment-Specific Shared Projects
+
+You can have **separate shared projects for dev/staging/prod**:
+
+| Portal Environment | Shared Project | Purpose |
+|--------------------|----------------|---------|
+| Dev | `ai-stack-portal-dev` | Development user stacks |
+| Staging | `ai-stack-portal-staging` | Staging user stacks |
+| Prod | `ai-stack-portal` | Production user stacks |
+
+Each portal deployment references its own shared project:
+- `portal-dev.ai.flexinit.nl` → `ai-stack-portal-dev`
+- `portal-staging.ai.flexinit.nl` → `ai-stack-portal-staging`
+- `portal.ai.flexinit.nl` → `ai-stack-portal`
+
+---
+
+## Migration from Legacy
+
+If you're currently using the legacy behavior (separate projects per user):
+
+### Option 1: Gradual Migration
+- New deployments use shared project
+- Old deployments remain in separate projects
+- Migrate old stacks manually over time
+
+### Option 2: Full Migration
+1. Create shared project
+2. Set project-level variables
+3. Redeploy all user stacks to shared project
+4. Delete old separate projects
+
+**Note**: Migration requires downtime for each stack being moved.
+
+---

+
+### Blockers Identified
+
+#### BLOCKER: Dokploy API Token Permissions
+
+**Symptom:** All Dokploy API calls return `Forbidden`
+
+```bash
+# Previously working
+curl -s "https://app.flexinit.nl/api/project.all" -H "x-api-key: $DOKPLOY_API_TOKEN"
+# Now returns: Forbidden
+
+# Environment endpoint
+curl -s "https://app.flexinit.nl/api/environment.one?environmentId=RqE9OFMdLwkzN7pif1xN8" -H "x-api-key: $DOKPLOY_API_TOKEN"
+# Returns: Forbidden
+```
+
+**Root Cause:** The API token `app_deployment...` has been revoked or has limited scope.
+
+**Impact:**
+- Cannot verify Docker image exists in registry
+- Cannot test name availability (requires `environment.one`)
+- Cannot create applications or compose stacks
+- Cannot deploy portal to Dokploy
+
+**Resolution Required:**
+1. Log into Dokploy UI at https://app.flexinit.nl
+2. Navigate to Settings → API Keys
+3. Generate new API key with full permissions:
+   - Read/Write access to projects
+   - Read/Write access to applications
+   - Read/Write access to compose stacks
+   - Read/Write access to domains
+4. Update `.env` with new token
+5. Update BWS secret (ID: `6b3618fc-ba02-49bc-bdc8-b3c9004087bc`)
+
+### Local Testing Results
+
+```bash
+# Health check - WORKS
+curl -s "http://localhost:3000/health"
+# {"status":"healthy","timestamp":"2026-01-13T13:01:46.100Z","version":"0.2.0",...}
+
+# Name check - FAILS (API token issue)
+curl -s "http://localhost:3000/api/check/test-stack"
+# {"available":false,"valid":false,"error":"Failed to check availability"}
+```
+
+### Required .env Configuration
+
+```bash
+# Added for shared project deployment
+SHARED_PROJECT_ID=2y2Glhz5Wy0dBNf6BOR_-
+SHARED_ENVIRONMENT_ID=RqE9OFMdLwkzN7pif1xN8
+```
+
+### Next Steps After Token Fix
+
+1. Verify `project.all` API works with new token
+2. Deploy portal to Dokploy (docker-compose.dev.yml)
+3. Test end-to-end stack deployment
+4. Verify stacks deploy to shared project
+5. Clean up test deployments
+
+### Commands Reference
