INSTALL

Replace the ENTIRE file:

/home/awitify/htdocs/awitify.com/assets/css/awitify.css

with this stylesheet.

This is a full stylesheet, not an add-on.

DESKTOP RESULT
- Full 100dvh app shell
- Black outer canvas
- Full-height left navigation panel
- Main content uses all remaining width and height
- Main content scrolls internally
- Small Spotify-like gaps between panels
- Dashboard profile becomes a large hero area
- No giant floating dashboard cards
- Account/Profile use the same app shell

MOBILE
- Sidebar automatically turns back into a compact top navigation
- Main content fills the remaining mobile viewport

Your config.php filemtime cache-buster should automatically change the CSS URL
after replacing the file.

No PHP changes.
No Vhost changes.
No PM2 restart.
