deploy.sh

#!/usr/bin/env bash
# ==============================================================================
# deploy.sh — Deploy the Curie showcase to GitHub Pages in one command.
#
# Usage:
#     ./deploy.sh your@email.com
#
# What it does:
#   1. Swaps REPLACE_WITH_EMAIL in index.html with your email
#   2. Initializes git repo locally
#   3. Creates public GitHub repo 'diffuser' under your account
#   4. Pushes files
#   5. Enables GitHub Pages on main branch
#   6. Prints the live URL (and opens it in your browser on Mac)
#
# Requirements (one-time setup):
#   - git (ships with macOS / comes with Xcode Command Line Tools)
#   - gh  (GitHub CLI — install with: brew install gh)
#   - Authenticated once: gh auth login   (just press enter a few times)
#
# Idempotent-ish: safe to inspect with --dry-run before committing.
# ==============================================================================
