+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+LisiLou Photography Portfolio is a lightweight, zero-framework photography portfolio website designed to integrate with Immich for image hosting and client gallery access. It's a single-page application with all code in one HTML file, using vanilla JavaScript and inline CSS.
+
+## Technology Stack
+
+- **Frontend:** Vanilla HTML5, CSS3, JavaScript (no framework)
+- **Server:** Nginx (Alpine-based)
+- **Deployment:** Docker + Docker Compose
+- **CI/CD:** Gitea Actions
+
+## Development Commands
+
+```bash
+# Start development server (serves at http://localhost:8080)
+docker compose up -d
+
+# Rebuild after code changes to src/index.html
+docker compose build && docker compose up -d
+
+# View container logs
+docker logs lisilou-portfolio
+```
+
+**Note:** Configuration (`config/`) and image (`public/images/`) changes are applied immediately without rebuild since they're mounted as volumes.
+
+## Architecture
+
+### Single-File SPA
+The entire application lives in `src/index.html` (~865 lines):
+- Lines 1-605: Inline CSS with CSS custom properties for theming
+- Lines 606-865: HTML structure and vanilla JavaScript
+
+### Configuration-Driven Content
+All site content is loaded dynamically from `config/site.json` at runtime:
+- Site branding (title, tagline, logo)
+- Theme colors (applied to CSS variables)
+- Portfolio categories with Immich album links
+- Social media links
+- Client gallery access settings
+
+### Immich Integration
+The app serves as a gateway to Immich shared albums:
+- Portfolio categories link to Immich albums via `immichAlbumId`
+- Client gallery codes are Immich share IDs
+- Full URLs constructed as: `{baseUrl}{publicAlbumPrefix}{albumId}`
+
+### Multi-Tenant Support
+Multiple photographers can be supported via `config/profiles.json`, mapping domains to different configuration files.
+
+## Key Files
+
+| File | Purpose |
+|------|---------|
+| `src/index.html` | Complete SPA (CSS + HTML + JS) |
+| `config/site.json` | Runtime configuration for all content |
+| `config/profiles.json` | Multi-tenant profile routing |
+| `nginx.conf` | Caching rules, security headers, SPA routing |
+| `Dockerfile` | Multi-stage build (Node Alpine → Nginx Alpine) |
+| `.gitea/workflows/deploy.yml` | CI/CD pipeline |
+
+## Nginx Configuration Highlights
+
+- **Caching:** Images = 1 year, CSS/JS = 1 month, Config = 5 minutes
+- **Health Check:** `/health` endpoint for container monitoring
+- **SPA Routing:** Falls back to `index.html` for all unmatched routes
+- **Security Headers:** X-Frame-Options, X-Content-Type-Options, X-XSS-Protection, Referrer-Policy
