WEBBERDOO STARTER 2.0 — BROWSER INSTALLER

Deployment target example:
https://starter.webberdoo.com

Recommended shared-host deployment:
1. Upload the full application, including vendor/ and public/build/.
2. Point the subdomain document root at the application's public/ directory.
3. Ensure the project root and var/ are writable by PHP during installation.
4. Create an empty MySQL/MariaDB database and database user in the hosting panel.
5. Visit https://starter.webberdoo.com/install/
6. Complete Environment → Application → Database → Email → Administrator.
7. The final step runs Doctrine migrations internally; no SSH or shell command is required.
8. On success the installer writes APP_INSTALLED=1 to .env.local and var/installed.lock.
9. /install/ then returns 404 and public/index.php no longer redirects there.

Security / configuration notes:
- The installer never overwrites the committed .env file.
- It creates/updates only .env.local and preserves unrelated existing .env.local values.
- A fresh production APP_SECRET is generated automatically when needed.
- DATABASE_URL uses the database server version detected by SELECT VERSION().
- Passwords are never written to installer log files.
- SMTP may be configured during installation or deferred.
