v1.13.0

Added

• Laypeople-friendly web installer wizard. The welcome screen now offers a Simple setup (auto-generated keys, safe localhost/HTTP defaults, straight to account creation) and an Advanced setup that walks every option step by step. A visible 23-language picker overrides browser detection and remembers your choice (right-to-left for Arabic and Persian), and navigation is flow-based rather than fixed step numbers.
• More can be configured from the web installer: SMTP email for the "forgot password" flow (EMAIL_SMTP_*, EMAIL_FROM_*), off-site WebDAV backups (WEBDAV_BACKUP_*), live currency rates (FIXER_API_KEY), the Web-Push contact address (VAPID_SUBJECT), and an automatically derived BASE_URL for password-reset links. A review screen summarizes access, email, single sign-on, and backups before writing.
• Web installer: download your .env. The final screen offers a one-click download of the generated .env file — the only backup of your encryption keys. In Simple setup, where the keys are never shown, the download leads until you've saved them.

Fixed

• Web installer no longer blocks non-SSO users. The pre-filled OIDC redirect URI was counted in the "all four fields or none" check, blocking every Advanced user who didn't configure single sign-on; only the three manually entered core fields are counted now.
• Web installer stays legible if its stylesheet can't load. Inline fallback design tokens (including a dark-mode variant) now precede the app stylesheet, so a misconfigured or missing tokens.css no longer renders the wizard as unstyled black-on-transparent text.
• Web installer: validation errors point at the offending field. Invalid inputs are now flagged with a red border and aria-invalid, and focus moves to the field — not just a message at the bottom of the step.
• Web installer: passwords and values with special characters survive. .env values containing spaces, #, $, or quotes are now quote-escaped so Docker Compose reads them back verbatim instead of truncating or misinterpreting them.
• Web installer no longer crashes if the container engine disappears mid-startup. The status poll now handles a vanished Docker/Podman binary gracefully instead of exiting.

Security

• Web installer rejects cross-origin requests. State-changing endpoints (writing .env, starting the container, creating the admin account) now require a loopback origin, guarding against DNS-rebinding/CSRF from a page visited while the installer is running.
