# 🚀 One-Command Dotfiles Deployment Script
#
# Quick deployment:     curl -sfL https://nothing.pink/zsh | bash
# Or for interactivity: bash <(curl -sfL https://nothing.pink/zsh) < /dev/tty
#
# What this script does:
# 1. Installs chezmoi if needed
# 2. Helps you set up your age encryption key
# 3. Deploys your complete dotfiles setup
# 4. Runs all automated configuration scripts
# 5. Validates the installation (37 checks)
#
# Prerequisites: Your age encryption key from ~/.config/age/chezmoi.txt
