 ### Deployment Process
 
-This project is now deployed to Cloudflare Pages for enhanced security.
-
 1. **Private repo** (`seedpgp-web`): Source code, development
-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.
+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

 ## Current Version: v1.4.0
 
-### Recent Changes (2026-01-30)
-- ✅ Extended session-key encryption to Restore flow
-- ✅ Added 10-second auto-clear timer for restored mnemonic
-- ✅ Added Hide button for manual clear
-- ✅ Removed debug console logs from sessionCrypto.ts
-
-### Known Limitations
-
-- GitHub Pages cannot set custom CSP headers (need Cloudflare Pages for enforcement)
-- Read-only Mode is UI-level only (not browser-enforced)
-- Session-key encryption doesn't protect against active XSS/extensions
-
-### Next Priorities (Suggested)
-
-1. Extend session-key encryption to Restore flow
-2. Migrate to Cloudflare Pages for real CSP header enforcement
-3. Add "Encrypted in memory" badge when encryptedMnemonicCache exists
-4. Document reproducible builds (git hash verification)
