AI OFFICE v6 - single-use installer, no PHP session token

1. Back up your current public_html/ai-office directory and AI Office database.
2. Extract this ZIP into public_html/ai-office (not a nested directory).
3. Do not overwrite or delete an existing _private/config.php.
4. Confirm fobbnbll_ai_office exists, and fobbnbll_jeffreydiana82 is assigned to it.
5. Create a separate SELECT-only MySQL user for fobbnbll_sales_tracker.
6. Visit https://bananatech-access.com/ai-office/setup.php if this is a fresh install.
7. Enter the real passwords only in your own hosted form. Create an admin password of 12+ characters.
8. After installation, visit login.php. Delete setup.php and check.php.
9. Keep _private inaccessible from the web; the included .htaccess blocks direct access.

If config.php already exists, setup is locked. Do NOT delete it to bypass the lock.
Instead, use login.php or diagnose existing configuration/database issues.

AI engine endpoint is initially disabled until configured separately.
No remote installation or MySQL connectivity is performed by this ZIP.
