%description
Ladybird is a truly independent web browser using a novel engine based on
web standards. It is not a fork of or based on Blink, Gecko, or WebKit.

Key features:
- Multi-process architecture for security and stability
- Independent LibWeb rendering engine
- Independent LibJS JavaScript engine
- Independent LibWasm WebAssembly implementation
- Sandboxed renderer and network processes

The browser consists of:
- Main UI process (Qt-based on Linux)
- WebContent renderer processes (one per tab)
- ImageDecoder process (for secure image handling)
- RequestServer process (for network requests)
- WebWorker process (for background JavaScript)

Note: Ladybird is currently in a pre-alpha state and is primarily suitable
for developers, testers, and early adopters. Many websites may not work
correctly yet.

%package        devel
Summary:        Development files for Ladybird browser components
Requires:       %{name}%{?_isa} = %{version}-%{release}

%description    devel
This package contains CMake configuration files, library symlinks, and headers
for developing applications that embed or extend Ladybird components.

Note: The Ladybird API is unstable and subject to change without notice.
This package is primarily intended for advanced users and contributors.
