BifrOSt-Apps

Latest change f35619cfe0419c596645328bf0e1b682ad3a4473 - Harden RÚV for the 0.1.1 candidate by Ólafur Búi Ólafsson

//! Minimal, sandboxed BifrOSt desktop application rendered with Dioxus.
//!
//! System decorations are disabled and a COSMIC-styled header bar is drawn by
//! the app itself, wired to real window controls, so the window matches other
//! COSMIC applications instead of showing GTK chrome.
