 ### Deployment Process

+This project is now deployed to Cloudflare Pages for enhanced security.
+
 1. **Private repo** (`seedpgp-web`): Source code, development
-2. **Public repo** (`seedpgp-web-app`): Built files for GitHub Pages
-3. **Deploy script** (`scripts/deploy.sh`): Builds + copies to dist/ + pushes to public repo
+2. **Cloudflare Pages**: Deploys from `seedpgp-web` repo directly.
+3. **GitHub Pages (Legacy)**: `seedpgp-web-app` public repo is retained for historical purposes, but no longer actively deployed to.
+
+### Cloudflare Pages Deployment
+
+1. Connect GitHub repo (`seedpgp-web`) to Cloudflare Pages.
+2. Build settings: `bun run build`, output directory: `dist/`.
+3. `public/_headers` file enforces Content Security Policy (CSP) and other security headers automatically.
+4. Benefits: Real CSP enforcement, not just a UI toggle.
