//! Configuration for srdwm's own session-lock UI
//! (`crates/wayland/src/native_lock.rs` does the actual rendering/input;
//! this is just the live-configurable knobs, same split `ThemeConfig`
//! already has between itself and the decoration-rendering code that
//! reads it).
//!
//! Not folded into `ThemeConfig` itself: that struct is `Copy` (read by
//! value on every decoration redraw), and a couple of these fields
//! (`fail_message`) need to be `String`/heap-allocated, which would force
//! every `ThemeConfig` copy to become a clone instead - cheap enough
//! given how rarely lock config is actually read (once per lock, not once
//! per frame), but no reason to pay that cost on every titlebar repaint
//! too.
