#!/usr/bin/env bash
# mTerminal install script — builds Electron app and installs for current user.
# Installs the unpacked Electron tree (no FUSE / AppImage needed at runtime).
# Usage:
#   ./install.sh                  # install to ~/.local
#   ./install.sh --system         # install to /usr/local (requires sudo)
#   ./install.sh --uninstall      # remove
