### Almost nothing, on purpose

A pure-black login screen: a live clock, username and password fields, and a power-off button. Nothing else to distract or break.

What it's built with, and why

## What it's built with, and why

QML SDDM's own greeter framework — no extra runtime, loads instantly at boot.

No daemon, no background process A theme is just static QML; nothing runs beyond the login screen itself.
