Introduces a dedicated layer-shell `WindowChromeSurface` that renders macOS-style traffic-light controls over the focused Sway window titlebar, replacing the old top-bar window controls. Adds theme tokens and a reusable `TrafficLightButton` component, updates shell QML/CMake wiring, and adjusts Sway titlebar padding/title format so window titles do not overlap the overlay. Window tracking was extended with focused-window geometry/deco/fullscreen properties plus backend refresh support so the chrome follows window movement and state changes in near real time.
Nebula.UI
Shared Qt Quick/QML design system for NebulaOS shells.
Desktop and the future Bigscreen shell should both import:
import Nebula.UI
This module contains reusable visual language only:
- colour, spacing, type, and motion tokens (
Theme) - generic controls (
NebulaButton,NebulaCard,NebulaIconButton,NebulaTextField,NebulaToolTip) - focus treatment (
FocusFrame) - compact vector icons (
NebulaIcon)
Do not put Desktop- or Bigscreen-specific chrome here (top bar, launcher, session flow).
Built as part of shells/desktop/shell. It is not a standalone application.
