# Treasure Panel - Build and install recipes
#
# Usage:
#   just build     - Build everything (main binary + plugin)
#   just install   - Install plugin to XFCE panel (system-wide, requires sudo)
#   just uninstall - Remove plugin from XFCE panel
#   just run       - Run the panel standalone
#   just clean     - Clean build artifacts
#
# The plugin .so embeds an absolute path to the launcher script (see PROJECT_ROOT).
# That script in turn execs the treasure-panel binary out of the same checkout's
# target dir. This means: build & install from the directory you intend to keep
# the source tree in. Move the source tree -> rerun `just build install`.
