+# Project Context for Claude Code
+
+## What is this project?
+
+This is a personal landing page for hiddenden.cafe, built with Astro. The owner is Mats, a gay furry developer who values self-hosting, privacy, and cozy aesthetics.
+
+## Key Design Principles
+
+1. **Cozy Aesthetic** - Warm colors, coffee/cappuccino theme, hidden den vibes
+2. **Self-Hosted** - Everything runs on personal infrastructure (homelab/VPS)
+3. **Privacy First** - No tracking, no external dependencies
+4. **Lightweight** - Static HTML/CSS, minimal JavaScript
+5. **Docker-Ready** - Easy deployment via containers
+
+## Owner Preferences
+
+- **Tech Stack**: Python/Flask normally, learning Astro for this project
+- **Deployment**: Docker containers pushed to personal Gitea registry at git.hiddenden.cafe
+- **Aesthetic**: Warm, comfy, coffee-themed, furry-friendly
+- **Content**: Honest and authentic, not corporate or sterile
+
+## Current Status
+
+The site currently has:
+- ✅ Landing page with hero section
+- ✅ About Hidden Den section
+- ✅ About Me section (Mats)
+- ✅ Services section (Gitea linked)
+- ✅ Support section
+- ✅ Docker deployment setup
+- ✅ Responsive design
+
+## What Might Be Added Later
+
+- Blog section for project updates
+- More self-hosted services as they're deployed
+- Payment/donation links when ready
+- Project showcase pulling from Gitea
+- Community features
+
+## Important Implementation Details
+
+### Color System
+All colors use CSS custom properties. To change theme, edit variables in `BaseLayout.astro`. Current palette is coffee/earth tones.
+
+### Content Updates
+Main content is in `src/pages/index.astro`. Each section is wrapped in semantic HTML with consistent styling via `.card` class.
+
+### Deployment Flow
+1. Develop locally with `npm run dev`
+2. Build with `npm run build`
+3. Create Docker image with `docker build`
+4. Push to Gitea registry
+5. Deploy on homelab/VPS
+
+### File Organization
+- `src/layouts/` - Reusable layouts (currently just BaseLayout)
+- `src/pages/` - Routes (index.astro = homepage)
+- `src/components/` - Reusable components (empty, ready for future use)
+- `public/` - Static assets (favicon, images)
+
+## Communication Style
+
+When discussing this project:
+- Be warm and friendly (matches the site vibe)
+- Use clear, direct language
+- Respect the furry community context
+- Focus on practical implementation
+- Acknowledge this is a learning project with Astro
+
+## Common Modification Patterns
+
+**Adding a service:**
+```astro
+<div class="service-item">
+  <h3><a href="https://service.hiddenden.cafe">🔧 Service Name</a></h3>
+  <p>Description of the service</p>
+</div>
+```
+
+**Adding a section:**
+```astro
+<section class="section new-section">
+  <div class="container">
+    <div class="card fade-in">
+      <h2>Section Title</h2>
+      <p>Content</p>
+    </div>
+  </div>
+</section>
+```
+
+**Modifying colors:**
+Edit the `:root` variables in `src/layouts/BaseLayout.astro`
+
+## Testing Checklist
+
+Before deploying changes:
+- [ ] `npm run dev` - Check locally
+- [ ] `npm run build` - Ensure build succeeds
+- [ ] `docker build -t hiddenden-cafe .` - Verify Docker build
+- [ ] Test on mobile viewport
+- [ ] Check all links work
+- [ ] Verify color contrast for accessibility
+
+## Owner's Workflow
+
+Mats typically:
+1. Works in bursts of creative energy
+2. Uses Docker for all deployments
+3. Pushes to personal Gitea at git.hiddenden.cafe
+4. Values complete control over hosting
+5. Prefers warm, personal styling over corporate design
+
+## Success Criteria
+
+The site should:
+- Load fast (static HTML)
+- Feel warm and welcoming
+- Accurately represent Mats and Hidden Den
+- Work on all screen sizes
+- Be easy to deploy via Docker
+- Require minimal maintenance
