#!/usr/bin/env bash
# codex-api-switch one-shot installer
#
# Usage:
#   bash install.sh                 # install CLI into ~/.local/bin
#   bash install.sh --app           # also build the macOS desktop app
#   bash install.sh --prefix DIR    # install into a custom directory
#
# Requirements:
#   - Codex installed on this machine (~/.codex/config.toml exists)
#   - Python 3.9+ (3.11+ recommended; older versions need `pip3 install tomli`)
