# ext-wallpaper — config-driven desktop background (GLOSSARY: "wallpaper").
# Standard-tier extension. Composites a solid colour + optional image file at
# SceneLayer::background (below everything else). Image path, fit mode, and
# background colour are driven by the [wallpaper] section of unbox.toml;
# hot-reloaded via Host::watch_file by DROP + RECREATE of the ui surface.
# input_transparent = true always (never steals clicks from windows above).
# Depends only on the kernel (Host::ui(), output events, watch_file).
ext_wallpaper_inc = include_directories('include')

# (subprojects/tomlplusplus.wrap). Force default_library=static so the installed
# `unbox` binary bakes it in (the wrap's own meson.build hardcodes shared, which
# would need libtomlplusplus.so at runtime). Same rationale as ext-keybindings.
