# This spec is designed for:
# - RHEL 10 / Rocky Linux 10 (using GCC 14.x)
# - Fedora 44 (using GCC 14.x)
#
# All these distributions ship with GCC 14.x which requires our C++20 concepts patch.
# The BuildRequires will naturally prevent building on older distributions.

%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.

Built specifically for RHEL 10, Rocky Linux 10, and Fedora 44.
Wayland-only - X11 support has been dropped.

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

Components:
- Main UI process (Qt6-based)
- Compositor process (rendering pipeline)
- WebContent renderer processes (one per tab)
- ImageDecoder process (secure image handling)
- RequestServer process (network requests)
- WebWorker process (background JavaScript)

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