# WorldLines — Linux double-clickable launcher.
#
# On most Linux desktop environments, marking this file executable
# (chmod +x) and double-clicking runs it in a terminal.
# This script:
#   1. Ensures `uv` + `worldlines` are installed (via worldlines.gg/install.sh).
#   2. Runs `uv tool upgrade worldlines` to pull the latest.
#   3. Execs `worldlines` so the TUI takes over the terminal window.
#
# Companion: WorldLines.command (macOS), WorldLines.bat (Windows).
