This repository is a React Native library providing native blur, vibrancy, and iOS 26+ liquid-glass effects for iOS, Android, and Web platforms. It implements six core components (BlurView, ProgressiveBlurView, VibrancyView, LiquidGlassView, LiquidGlassContainer, BlurSwitch) using React Native's New Architecture (Fabric) with platform-specific native implementations: UIVisualEffectView/UIGlassEffect on iOS, hardware-accelerated QmBlurView on Android, and CSS backdrop-filter on web. The library includes an example app demonstrating usage patterns and an Astro-based documentation site. A secondary spec-kit system provides internal development workflow guidelines but is not the primary product. The codebase exhibits strong cross-platform abstraction, graceful fallbacks, and maintainable native bridge patterns.
Kvantum is a Qt-based SVG theme engine for Linux desktop environments, implemented as a QStyle plugin that renders widgets using vector graphics from theme configuration files. The system includes a style plugin (Kvantum style), a GUI manager (Kvantum Manager) for installing, selecting, and configuring themes, and a preview application (Kvantum Preview) to showcase widget rendering. The style engine supports complex theming with configurable frame, interior, indicator, label, and size specs, as well as animations, blur effects, window dragging, per-application hacks, and desktop environment integration (KDE, LXQt, GNOME, etc.). The architecture is a monolith in the sense that the style plugin and two companion apps share common code paths (e.g., ThemeConfig, BlurHelper, WindowManager), but the codebase is split across Qt4, Qt5, and Qt6 variants with significant duplication. The primary data flow is: user selects a theme → Kvantum Manager writes config files → Kvantum style reads .kvconfig and .svg assets at runtime → Qt applications render widgets according to the theme specifications. External dependencies are Qt (≥6.6), QSvgRenderer, and optionally KDE's KWindowEffects for blur.
